 The [[adi>AD9467]] is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC) with a conversion rate of up to 250 MSPS. This reference design includes a data capture interface and the external DDR-DRAM interface for sample storage. It allows programming the device and monitoring its internal status registers. The board also provides other options to drive the clock and analog inputs of the ADC. This can be done by programming the [[adi>AD9517-4]] clock chip and/or setting up the ADL5565 differential amplifier respectively.  The [[adi>AD9467]] is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC) with a conversion rate of up to 250 MSPS.

-===== Supported Carriers =====+==== Clock Selection ==== 
 + 
 +The board provides three (some modification maybe necessary) possible clock path for clocking the AD9467.  
 + 
 +The **default clock input** circuitry is derived from a simple transformer-coupled circuit using a high bandwidth 1:1 impedance ratio transformer (T201) that adds a very low amount of jitter to the clock path. The clock input (J201) is 50 Ω terminated and ac-coupled to handle single-ended sine wave types of inputs. The transformer converts the single-ended input to a differential signal that is clipped before entering the ADC clock inputs. 
 + 
 +The evaluation board can be set up to be clocked from the **crystal oscillator**, Y200. This oscillator is a low phase noise oscillator from Vectron (VCC6-QCD-250M000). If this clock source is desired, install C205 and C206 and remove C202. Jumper P200 is used to disable the oscillator from running. 
  
-^ Board     ^ XPS     ^ Vivado     ^ +A **differential LVPECL or LVDS clock driver** can also be used to clock the ADC input using the [[adi>media/en/technical-documentation/data-sheets/AD9517-4.pdf|AD9517]]. Populate C304, C305, C306, and C307 with 0.1 µF capacitors for one drive option or the other and remove C209 and C210 to disconnect the default clock path inputs. The AD9517 has many SPI-selectable options that are set to a default mode of operation. Consult the AD9517 data sheet for more information about these and other options.

-==== Running Demo (SDK) Program ==== +===== Using the HDL reference design =====
-To begin, connect the AD9467-FMC-EBZ board to the FMC-LPC connector of ML605 (see image below) or KC705 or Zed board. If using VC707 connect to the FMC1-HPC. Connect power and two USB cables from the PC to the //JTAG// and //UART// USB connectors on the edge of the ML605. ** The demo program uses the default board configuration that uses an external clock (AD9517 is powered down). ** However, since AD9517 is still access-able via SPI, the SDK program configures it for a pass through mode. Connect a clock source to the CLKIN SMA connector and a signal source to the AIN SMA connector of the FMC card. After the hardware setup, turn the power on to the ML605.+

-The reference design contains an example on how to:

-  * Initialize the AD9467 HDL core 
-  * Test the ADC communication using the test patterns and PRBS sequences generated by the AD9467 
-  * Capture data from the AD9467 using DMA transfers 
  
-After the ADC test patterns and PRBS sequences are verified, if no errors are present, the reference design continuously reads data from the ADC. The ADC data can be viewed using the Chipscope project located in the "//Chipscope//" folder provided in the HDL Reference Design.
