2.3. Datapath Modes
The JESD204B IP generates a single link with a single lane and up to a maximum of 8 lanes. If there are two ADC links that need to be synchronized, you have to generate two JESD204B IP cores and then manage the deterministic latency and synchronization signals, like SYSREF and SYNC_N, at your custom wrapper level.
The JESD204B IP supports duplex mode only if the LMF configuration for ADC (RX) is the same as DAC (TX) and with the same data rate. This use case is mainly for prototyping with internal serial loopback mode. This is because typically as a unidirectional protocol, the LMF configuration of converter devices for both DAC and ADC are not identical.
