| + | ===== General Description ===== | ||
| + | The ADMX1001 and ADMX1002 modules are ultra-low distortion and low-noise signal generators. They have a frequency range of up to 40 kHz when not using the digital pre-distortion (DPD) algorithm. If the DPD algorithm is enabled for signal generation, they can generate tones up to 20 kHz with -130dB typical of total harmonic distortion (THD) at 1 kHz. In addition to signal generation, the ADMX1001 includes a differential input acquisition channel to measure a signal of choice. | ||

| + | ===== ADMX100X General Description ==== | ||
| + | The ADMX100X module shown in Figure 8 is an ultra-low distortion and low noise autonomous digitally controller sinewave signal generator, generating the purest sinusoidal differential signals in its class by exploiting a digital pre-distortion | ||
| + | |||
| + | ==== Source Channel === | ||
| + | |||
| + | Both the ADMX1001 and ADMX1002 offer a multi-tone frequency range of up to 40 kHz. The ADMX100X can perform the digital pre-distortion (DPD) algorithm to provide an ultra-low distortion and low noise signal from 30Hz to 20kHz. The module generates an ultra-low distortion performance up to −130dB at 1 kHz with DPD, and −118dB at 1 kHz without DPD. The ADMX100X module has the capability to perform in DC, dual tone, and arbitrary waveform generation mode. | ||
| + | |||
| + | For applications that require different voltage and current levels, the sense lines can be connected to an external buffer or level-shifting circuitry to permit the entire forward signal chain to be corrected. | ||
| + | |||
| + | The module is configurable through a flexible digital interface allows for easy integration into any system. In addition, ATE control bus lines are available for maximum control of the signal in timing-critical applications. | ||
| + | |||
| + | ==== Acquisition Channel === | ||
| + | |||
| + | The ADMX1001 module offers an acquisition channel input, which can be accessed using the secondary ADC interface to read the conversion data directly. | ||
| + | |||
| + | ADMX1001 can act as master or slave when supporting coherent test signal generation and offers an auxiliary ADC input, operating at 256 ksps. | ||
| + | |||
| + | The highly integrated data acquisition solution provides 7 programmable gain options with a maximum input range of ±7.5V differential and a maximum input common mode range of ±7V. A 4th order anti-aliasing filter provides rejection up to −130dB. The total dynamic range of the acquisition channel is up to 128dB with a −115dB typical THD with a 1kHz input tone at full scale. | ||

| + | </ | ||
| + | |||
| + | ===== Operation Modes ===== | ||
| + | ==== Single Tone Generation ==== | ||
| + | ADMX100X module is specially designed to generate an ultra-high purity sine waveform from 30 Hz up to 20 kHz by a patented digital pre-distortion (DPD) algorithm method. In addition, the module can generate high-purity signals up to 40kHz without DPD. | ||
| + | |||
| + | === Default Mode (without DPD) === | ||
| + | This is the default mode when a new frequency and/or amplitude is loaded into the register, and the generate register or trigger pin is toggled. | ||
| + | The ADMX100X module performance exceeds the native performance of the components due to its architecture. | ||
| + | This is the operation mode for arbitrary waveform generation as well. | ||
| + | |||
| + | === With DPD Mode === | ||
| + | If ultra-high performance is needed the digital pre-distortion (DPD) algorithm can be enabled by software or hardware. The DPD process requires no external reference inputs and exploits a patented differential temporal and amplitude sensing method. When combined with our novel DSP algorithm, this eliminates the electrical measurement errors that would normally limit the performance. The DPD algorithm range frequency goes from 30Hz up to 20kHz, with an amplitude range of up to 3.62VRMS. Figure 4 shows the ADMX100X module THD before and after DPD. Moreover, Figure 5 and Figure 6 show the FFT of an ADMX100X module at 1kHz with 2Vrms before and after DPD. | ||
| + | |||
| + | === Sense Connection === | ||
| + | The DPD algorithm of ADMX100X requires the sense inputs to be connected to the output of ADMX1001 and ADMX1002 which will be used in the process routine of ADMX1001 and ADMX1002 to generate an ultra-high purity sine waveform. The sense connection can be used to combine a user buffer circuit as part of the signal generation in the DPD process by connecting the sense input to the output of the user’s buffer stage. | ||

| + | </ | ||
| + | |||
| + | ==== DC Generation ==== | ||
| + | ADMX100X is capable of generating differential DC output signals up to 11.3V DC between Vp and Vn. The output level can be adjusted in 1µV resolution steps, and the software will verify if the entered parameters are valid by using the valid register. The DC output will be continuously generated after the run command is received and can be stopped by sending a stop command. | ||
| + | |||
| + | ==== Dual-tone Waveform Generation ==== | ||
| + | Two sine wave tones can be generated from 30Hz to 20kHz. The dual-tone waveform generation can be performed in burst mode or continuous mode. The dual-tone waveform frequency resolution can be programmed with 1 µHz resolution while the amplitudes can be programmed with 1 µV resolution. | ||
| + | |||
| + | ==== Arbitrary Waveform Generation ==== | ||
| + | An arbitrary waveform can be programmed by the user. The AWG signal can be programmed up to 20s long and will be stored in volatile memory. Continuous AWG generation can be performed by looping back the waveform stored in memory. ADMX100X contains a 27kHz low pass filter on its output allowing AWG waveforms to be generated within this band. Signals generated in the band will be within a 5% tolerance. | ||
| + | |||
| + | ==== Acquisition Channel ==== | ||
| + | The highly integrated data acquisition solution provides 7 programmable gain options with a maximum input range of ±7.5V differential and a maximum input common mode range of ±7V. A 4th order anti-aliasing filter provides rejection up to −130dB. The total dynamic range of the acquisition channel is up to 128dB with a −115dB typical THD with a 1kHz input tone at full scale. | ||
| + | |||
| + | ==== SPI Control ==== | ||
| + | An overview of the SPI control mode features is as follows: | ||
| + | * Standard SPI Mode 3 interface for register access, where the ADC always behaves as an SPI slave. | ||
| + | * Indication of a new conversion via the DRDY pin output. | ||
| + | * A second method allows the user to merge the ready signal within the DOUT output stream, which allows a reduction in the number of lines across an isolation barrier. | ||
| + | * Reading back conversions can be performed by writing 8 bits to address the ADC register and reading back the result from the register. | ||
| + | * Continuous readback mode, which is enabled via an SPI write. There is no need to supply the 8 bits to address the ADC_DATA register (Register 0x2C). Data readback occurs on the application of SCLK. The DRDY pin indicates that a conversion result is complete and can be used to trigger a readback of the conversion result. | ||
| + | * In continuous read-back mode, there is the option to append either the 8-bit status header or an 8-bit CRC check, or both. | ||
| + | |||
| + | ==== Additional Features ==== | ||
| + | |||
| + | === Burst/ | ||
| + | In burst mode, the tone will only be generated for a defined length of time while in continuous mode the waveforms will be generated continuously until the STOP command is sent. | ||
| + | |||
| + | === Profiles === | ||
| + | Once a digital pre-distortion (DPD) algorithm is used for a given frequency or amplitude, the DPD parameters can be saved into the non-volatile profile memory. If you change the parameters of your signal without storing the previous DPD parameters, these parameters will be lost once a new frequency or amplitude is loaded into the module. When generating a new combination of frequency and amplitude (also known as a profile) DPD algorithm can be performed to generate a high-purity signal and can be stored to be later recalled. Up to 16 such signals can be stored and can be recalled easily by hardware or software. This allows fast-high purity frequency switching. Profiles 1 through 15 can store any signal type (single tone, single tone with DPD, DC, dual tone, etc.), but profile 16 is reserved for an AWG signal type only. | ||
| + | |||
| + | ==== ADMX100X Limitations ==== | ||
| + | - The DPD algorithm cannot be used for frequencies above 20 kHz. | ||
| + | - The DPD algorithm does not work with signals lower than 100mVrms. | ||
| + | - Frequencies above 40 kHz cannot be selected. | ||
| + | - Amplitude above 3.5Vrms cannot be set. | ||
| + | - Only voltages below 3.5Vrms can be set for frequencies less than 10.5 kHz. | ||
| + | - Voltages above 2.5Vrms cannot be set for frequencies greater than 15.5 kHz. | ||
| + | - Voltages above 2Vrms cannot be set for frequencies greater than 20.5 kHz. | ||
| + | - Only voltages below 1Vrms can be set for frequencies greater than 20.5 kHz | ||

| + | ===== Applications Information ===== | ||
| + | |||
| + | ==== ATE Control Interface ==== | ||
| + | The Automatic Test Equipment (ATE) control interface can be used to provide a simple protocol for initiating an instruction to perform a DPD calibration or signal generation by driving and monitoring pins on the module. The test parameters, like the amplitude and frequency of the signal, must still be loaded through SPI. | ||
| + | |||
| + | **Table 3. ATE Pin Assignment and Function**\\ | ||
| + | |||
| + | ^Connector | ||
| + | |EN | ||
| + | |READY | ||
| + | |TRIG |Input | ||
| + | |VALID | ||
| + | |CAL | ||
| + | |OT | ||
| + | |SYNC_MODE | ||
| + | |::: |::: | 0 - uses External Sync Clock | | ||
| + | |SYNC_IN | ||
| + | |SYNC_OUT | ||
| + | |||
| + | ==== Test Sequence ==== | ||
| + | There are two possible test sequences: Signal Generation & DPD Calibration. It is not necessary to run a DPD calibration phase before every signal generation sequence. The following examples use all the module' | ||
| + | |||
| + | ==== Signal Generation ==== | ||
| + | The procedure below should be followed for stimulus generation: | ||
| + | - Turn-on power supplies to modules (+3.3V & +/-9V). | ||
| + | - Set Enable (EN) High - Enables internal supplies within the module. | ||
| + | - Wait until module initialization has completed (READY=1). | ||
| + | - Load serial test configuration data. | ||
| + | - Low to high TRIG transition initiates the test sequence. | ||
| + | - Module outputs synchronization (SYNC_OUT) pulses over the period the VALID signal is held high. | ||
| + | - Low to High transition of the VALID signal indicates the start of the stimulus. | ||
| + | - High to Low transition of the VALID signal indicates the end of the stimulus. | ||
| + | |||
| + | The same test can be run multiple times without reloading the configuration by repeating steps 5 through 8. Once new test configuration data has been reloaded via SPI, the new configuration will need to be revalidated before signal generation can resume without error. | ||
| + | |||
| + | ==== Calibration ==== | ||
| + | To achieve the highest signal purity, a DPD calibration phase must be run at least once before generating an output signal. The DPD calibration data is normally stored in volatile memory and therefore must be re-run after every power supply sequence or once there is a change in the amplitude, frequency, and common-mode voltage settings. | ||
| + | |||
| + | The procedure below should be followed for calibration: | ||
| + | - Enable power supplies to modules (+3.3V & +/-9V). | ||
| + | - Set Enable (EN) High - Enables internal supplies within the module. | ||
| + | - Wait until module initialization has completed (READY=1). | ||
| + | - Load serial test configuration data. | ||
| + | - Set CAL signal High to start module DPD Calibration procedure. | ||
| + | - Monitor the high to low transition of the VALID signal to indicate the end of calibration. | ||
| + | - Start generating an output signal. | ||
| + | ==== Coherent Sampling ==== | ||
| + | Coherent sampling describes the sampling of a periodic signal, where an integer number of its cycles fit into a predefined sampling window. This technique is very useful to get the best achievable results when evaluating the dynamic performance of analog-to-digital converters (ADCs). To facilitate coherent sampling, the module can synchronize its signal generation to an external clock by doing the following: | ||
| + | - Connect the SYNC_Mode pin to GND by inserting a jumper in the 2-3 position of P12. | ||
| + | - Connect the SYNC_IN pin to the SMA input by inserting a jumper in the 2-3 position of P13. | ||
| + | - Apply a 100 MHz external clock to J7 to synchronize the generated signal to the external clock. | ||
| + | Notes: | ||
| + | * The external clock must be turned on first before applying power to the EVAL-ADMX100X-FMCZ. | ||
| + | * Take note of the logic level limits below for the SYNC_IN and SYNC_OUT pins. | ||
| + | * Trigger needs to be set high to start generating the signal. | ||
| + | * During Coherent Sampling, SYNC_IN must have a 100 MHz clock frequency with a 50% duty cycle. | ||
| + | * Although less common, coherent sampling may also be performed by synchronizing the analyzer from the clock generated from the module (SYNC_OUT). | ||
