Clock generation for AD9680-LF1000EBZ Evaluation board and Third part FPGA development board

Thread Summary

The user inquires if the onboard clock generator of the AD9680-LF1000EBZ is sufficient for interfacing with a third-party FPGA board for DSP with JESD204B. The final answer indicates that while the AD9680 has an on-board crystal oscillator for the sample clock, a separate low-jitter clock source (e.g., LTC6951, LTC6952, HMC7044, AD9528) is required for the reference clock. The HMC7044 is recommended for ultra-low jitter and JESD204B clock generation. The user confirms the need for in-stock evaluation boards for the recommended clock generators.

Hi,
We are planning to purchase an AD9680-LF1000EBZ evaluation board which is to be interfaced with our third-party FPGA development board. My question is: whether the onboard clock generator of the AD9680-LF1000EBZ evaluation board is sufficient for all the required clock signals (Like sample and reference clock for ADC and clocks for FPGA) to carry out DSP with JESD204B interface using the above boards. Or is an additional clock evaluation board needed? If yes then, please suggest a suitable and economical model of it. I explored the ADI website and found the following clock evaluation boards but not sure which one is the most suitable one. These boards are AD9525, AD 9528, AD9526-0, and HMC 7044. Please help. Thanks.
