1.2. Hardware Setup for Stratix V Advanced Systems Development Kit

Figure 1. Hardware Setup

A Stratix V Advanced Systems Development Kit is used with the ADI AD9680 daughter card module 3 attached to the FMC connector on the development board.

  • The AD9680 EVM derives power from 4.5 V power adaptor.
  • The FPGA and ADC device clock is supplied by external clock source card through the SMA connectors on the AD9680 EVM.
  • Both the FPGA and ADC device clock must be sourced from the same clock source card with two different frequencies, one for the FPGA and one for ADC.
  • For subclass 1, the FPGA generates SYSREF for the JESD204B IP core as well as the AD9680 device.


Figure 2. System Diagram

The system-level diagram shows how the different modules connect in this design.

In this setup, where LMF=421, the data rate of transceiver lanes is 12.5 Gbps. An external clock source card provides 312.5 MHz clock to the FPGA and 1250 MHz sampling clock to AD9680 device.



3 The AD9680 EVM used in this report differs from the production version of AD9680-1000EBZ EVM. However, there is no difference in terms of functionality between these two EVM.
