Figure 2-1: Typical System Application for JESD204B IP Core
The JESD204B IP core utilizes the Avalon-ST source and sink interfaces, with unidirectional flow of data,
to transmit and receive data on the FPGA fabric interface.

Key features of the JESD204B IP core:
• Data rate of up to 12.5 Gbps
• Run-time JESD204B parameter configuration (L, M, F, S, N, K, CS, CF)
• MAC and PHY partitioning for portability
• Subclass 0 mode for backward compatibility to JESD204A
• Subclass 1 mode for deterministic latency support (using SYSREF) between the ADC/DAC and logic
device
• Subclass 2 mode for deterministic latency support (using SYNC_N) between the ADC/DAC and logic
device
• Multi-device synchronization
