Why use FPGAs?
As technology evolves, higher conversion and communication speeds are obtained, but operating a part at it’s maximum potential can rise certain problems:uCustom communication protocoluAccurate timinguHigh Speed Data TransfersuThe need for an operating system
Using FPGAs, everything can be customized to operate the part at it’s best. Custom IP Cores can be designed according to the datasheet specifications, also providing great portability between different FPGA families.
What solutions does ADI offer?
Depending on the complexity of the part and the need for fast prototyping, Analog Devices offers the following type of evaluation platforms:
uDigilent Peripheral Modules – Pmods®uEvaluation Boards and FMC InterposersuFMC Evaluation Boards
Reference designs
u Reference designs available at http://wiki.analog.comu Customer support available at http://ez.analog.comu Documentation including schematics can be downloaded
from the wiki page

Interposers and Evaluation BoardsAnalog Devices provides 3 types of Interposers for connecting ADI Evaluation Boards to Xilinx FPGAs:
u AD-DAC-FMC Adapteru AD-ADC-FMC Adapteru FMC-SDP Interposer
All 3 Interposers are used to interface ADI Evaluation Boards with Xilinx Boards that have an FMC Connector.
Why the need for a high-speed converter-to-FPGA serial interface?
uSimplification of overall system designl Smaller/lower number of trace routes, easier to route board designs
uReduction in pin count – Both the Tx and Rx sidel Move from high pin count low speed parallel interfaces to low pin
count high speed serial interfacesl Embedded clock incorporated to even further reduce pin count
uReduction in system costsl Smaller IC packages and board designs lead to lower cost
uEasily scalable to meet future bandwidth requirementsl As geometries shrink and speed increases, the standard adapts
What is JESD204?
u“SERDES” is often used instead of JESD204. SERDES is simply a generic name for any serial interface.
uJESD204 is a high speed, point to point, serial interface used to interconnect 2 (or more) devices.l ADC to digital receiverl Digital source to DACl ADC and DAC to Digital enginel Digital source to digital receiver
uHow is it different than previous data converter interfaces?l A single primary interface can be used to pass all data, clocking
and framing information.uThe clock and frame information are embedded in the data stream.uNo need to worry about set up and hold time between data and clock.uOne PCB trace (differential) can route all bits.

What is the JEDEC Standard 204 (JESD204)
uJESD204 is a standard defining a multi-gigabit serial data link between converters and a receiver (commonly FPGA or ASIC)
uJESD204 (April 2006) – original standard defining 1 lane, 1 linkl Defined transmission of samples across a single serial lane for
multiple converters at speeds up to 3.125 Gbps
What is the JEDEC Standard 204 (JESD204A)
uJESD204A (April 2008) – 1st revision expanding standard to multiple links and multiple lanesl Revision adds capability for multiple aligned serial lanes for
multiple converters at speeds up to 3.125 Gbps
What is the JEDEC Standard 204 (JESD204B)
uJESD204B (August 2011) – 2nd revision utilizes a device clock and adds measures to ensure deterministic latencyl Supports multiple aligned serial lanes for multiple converters
at speeds up to 12.5 Gbps

AD-DAC-FMC AdapterThe AD-DAC-FMC-ADP adapter board allows any of Analog Devices' DPG2-compatiable High-Speed DAC Evaluation Boards to be used on a Xilinx® evaluation board with a FMC connector. The adapter board uses the Low Pin Count (LPC) version of the FMC connector, so it can be used on either LPC or HPC hosts (such as the ML605, SP605, KC705, etc.)
For a list of compatible evaluation boards, please see the "DPG2"
information on our Data Pattern Generator (DPG) High-Speed DAC Evaluation Platform
page.

After programming the FPGA using iMPACT, the user is ready to launch a TCL script which will save a wav file on the HDD.
When the script is running, 20 seconds of audio data is recorded at 25000 Hz sample rate, and saved in the DataCapture folder as EVAL_ADMP441Z_Demo.wav.
The user can modify the sample rate and the duration of the recording by modifying parameters in main.c.
