+ | ===== Getting Started with the AD9142A-M5375-EBZ Evaluation Board and Software ===== | ||
+ | ==== What's in the Box ==== | ||
+ | * AD9142A-M5375-EBZ | ||
+ | * Evaluation Board CD | ||
+ | * Mini-USB Cable | ||
+ | ==== Recommended Equipment List ==== | ||
+ | * +5Vdc, Power Supply | ||
+ | * 2 Sinusoidal Clock Sources | ||
+ | * Spectrum Analyzer | ||
+ | * Data Pattern Generator Series 2 or 3 (DPG) | ||
+ | ==== Introduction ==== | ||
+ | The AD9142A-M5375-EBZ connects to a DPG for quick evaluation of the AD9142A, a high-speed, signal processing Digital to Analog Converter. The DPG automatically formats the data and sends it to the AD9142A-M5375-EBZ, | ||
+ | ===== AD9142A Evaluation Software ===== | ||
+ | The AD9142A Evaluation Board software has an easy-to-use legacy graphical user interface (GUI), but ACE, a newer evaluation software from ADI, is the preferred evaluation software. Both are included on the Evaluation Board CD. Alternatively, | ||
+ | ===== Hardware Setup ===== | ||
+ | Connect +5.0V to P5, GND to P6. One low phase noise high frequency clock source should be connected to the SMA connector, J1 (AD9516_CLKIN). The other low phase noise high frequency clock source should be connected to the SMA connector, J15 (LO_IN), and the spectrum analyzer should be connected to the SMA connector, J6. The evaluation board connects to the DPG through the connectors P1 and P2. The PC should be connected to the EVB using the mini-USB connector XP2 after installation of the Evaluation Board software. Figure 1 shows the block diagram of the set-up. | ||

Set the frequency of the DAC clock signal generator to 1400MHz, and the output level to 6dBm. The spectrum analyzer can be configured with Center Frequency = 2050 MHz, Span = 200 MHz, and Resolution Bandwidth of 30 kHz. Choose Input Attenuation to be 24dB. This can be adjusted later if indications are that the analyzer is causing degradations. \\ \\ | ||

+ | ===== SPI SOFTWARE ===== | ||
+ | The AD9142A SPI software is conveniently organized in a series of tabs that groups registers according to their functions. In this way, all registers associated with the digital functions, for example, are on the “Digital Functions” tab. All registers associated with the PLL are on the “PLL” tab, and so on. Normally the “Quick Start” tab is sufficient for a quick evaluation. The most frequently used register controls are included on this tab. A full description of each register and its settings is given in the AD9142A data sheet. Some of the registers and their functions are described here as they pertain to the AD9142A evaluation board. Please note that some of the screen images in this document may not match exactly with the latest revision of the software, due to ongoing improvements and enhancements to the software. \\ | ||
+ | The full screen layout is shown in Figure 5. The tabs can be seen across the top of the work area, and four function buttons in the menu area. “Save Registers to File” and “Restore Registers from File” allow the user to save the current register settings into a file for later uses. A register is immediately updated when the value in the control is changed. Switching between tabs does not update register values. “Read All Registers” can be used to monitor a resister with changing readback values. “ Record Sequence” allows the user to record a series of SPI writes in a particular order and to play back the sequence later. A short description of the register is shown in the status bar on the bottom of the work area when the mouse curser hovers over the control. Some of the tabs are discussed below. | ||
+ | ==== Quick Start ==== | ||
+ | The “Quick Start” tab has selections that apply to the general configuration of the DAC. Reset DAC is recommended every time when the DAC is powered on or reset. Interpolation Rate allows the user to select among the 3 interpolation modes (2X, 4X, and 8X). When the NCO is used, set NCO Enable to 1, fill in the NCO frequency tuning word with the desired value and toggle SPI Update Request. To use the Fs/4 modulation, turn on the Fs/4 Modulation control. FIFO SPI Reset Request sets the FIFO with the requested value through a SPI command. The FIFO Level Read Back should reflect the actual FIFO level after the FIFO SPI Reset Request. Note loading/ | ||

+ | ==== PLL ==== | ||
+ | The “PLL” tab includes all the PLL control registers. The recommended settings for the best performance is PLL Charge Pump Current = 7 and PLL LOOP BW = 7. The user needs to follow the sequence below to enable the PLL. | ||
+ | 1. Choose the desired divide ratios in the Loop Divider and the VCO Divider. \\ | ||
+ | 2. Set PLL Charge Pump Current and PLL Loop BW settings to 7. \\ | ||
+ | 3. Set the PLL Mode to Manual. \\ | ||
+ | 4. Turn on PLL Enable. \\ | ||
+ | 5. Set the PLL Mode to Auto. \\ | ||

+ | |||
+ | Note: When viewing the modulator output, a local oscillator (LO) must be connected to J15 (”LO_IN”) to properly modulate the signals | ||
+ | ===== ACE Software ===== | ||
+ | The ACE software is organized to allow the user to evaluate and control the AD9122A evaluation board. The “Initial Configuration” wizard, which is only available for certain boards, controls the DAC and PLL setups. Block diagram views of the board and chip contain elements that can be used to vary parameters like ref current and data format. These parameters can be changed using check boxes, drop down menus, and input boxes. Some parameters do not have settings shown in the diagram. Double click on the parameter to view the available settings, seen with the NCO settings below. | ||
+ | |||
+ | {{ : | ||
+ | <WRAP clear> | ||
+ | </ | ||
+ | <WRAP centeralign> | ||
+ | |||
+ | In addition, some parameters can be enabled or disabled. This feature is evident by the color of the block parameter. For example, if the block parameter is dark blue, the parameter is enabled. If it is light grey, it is disabled. To enable or disable a parameter, click on it. | ||

+ | More direct changes to registers and bit fields can be made in the memory map, which is linked from the chip block diagram through the “Proceed to Memory Map” button. In this view, names, addresses, and data can be manually altered by the user. | ||

+ | <WRAP centeralign> | ||
+ | |||
+ | ACE also contains the Macro Tool, which can be used to record register reads and writes. This is executed in the memory map view or with the initialization wizard. To use, check the “Record Sub-Commands” checkbox and press the record button. Changes in the memory map, which are bolded until they are applied to the part, are recorded as UI commands by the macro tool once the changes are made. Changed register write commands for the controls are also recorded. Hit “Apply Changes” to execute the commands and make changes in the memory map. To stop recording, click the “Stop Recording” button. A macro tool page with the command steps will be created. The macro can be saved using the “Save Macro” button so that it may be loaded for future use. | ||

+ | | {{ : | ||

+ | </ | ||
+ | <WRAP centeralign> | ||
+ | |||
+ | The raw macro file will be saved using ACE syntax, which is not easily readable. To remedy this, the ACE software download includes the Macro to Hex Conversion Tool. The user can choose to include or exclude register write, reads, and/or comments in the conversion. The file pathways for the source and save paths should be the same, except that one should be an .acemacro file and the other should be a .txt file. The “Convert” button converts and opens the converted text file, which is easier to read. The conversion tool can also convert back to an .acemacro file if desired. | ||
