I am wondering what are the input clocking requirement for AD9680. Which clock generating devices on the custom design PCB would be suitable and compatible with AD9680.

    Hi  
    

    Thanks for your interest in AD9680.
    

    For the input clocking requirements of the AD9680, please refer to the "CLOCK INPUT CONSIDERATIONS" section in the device's datasheet. This section provides detailed guidance on acceptable clock types, levels, and jitter performance necessary for optimal ADC operation.
    

    For generating a suitable and compatible clock on your custom PCB, we recommend using the HMC7044. It is a high-performance, ultra-low jitter clock generator that supports JESD204B subclass 0 and 1, making it an excellent choice for clocking the AD9680 in high-speed data converter applications.
