Synchronization is required in many systems like Multi-antenna communications systems, Phased array radars, Magnetic resonance imaging etc. Most systems that require multiple synchronized signal chains also require synchronization of analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

If the Latency between the JESD204B interface in the FPGA and DAC Output is always fixed and constant, then we say that the DAC output is synchronized. Latency from the frame-based data input at the TX to the frame-based data output at the RX. Latency should be programmable and repeatable over power cycles and re-sync events.
