JESD204B MegaCore IP

From Intel® (formerly Altera)

Jump-Start Your JESD204B Implementation

Intel provides the easiest to use JESD204B serial interface in the industry across multiple products –from low-cost or low-power to high-performance FPGAs and SoCs. With our unique implementation of a full transport layer, design engineers no longer need to analyze documentation to integrate or develop a transport layer solution. This can save weeks in logic design and verification.

Intel’s hardware interoperability testing of our JESD204B MegaCore® intellectual property (IP) with analog-to-digital converter (ADC) and digital-to-analog converter (DAC) vendors as well as RFICs and analog front ends, including Analog Devices Incorporated (ADI) and Texas Instruments (TI) gets you to market faster.

Block Diagram

The JESD204B MegaCore IP utilizes the Avalon® Streaming (Avalon-ST) source and sink interfaces with unidirectional flow of data to transmit and receive data on the FPGA fabric interface.


The JESD204B MegaCore IP delivers the following key features:

  • Lane rates of up to 12.5 Gbps (characterized and certified to the JESD204B standard), and lane rates up to 15 Gbps (uncharacterized and not certitied to the JESD204B standard)
  • Run-time reconfiguration of JESD parameters (L, M, F, S, N, K, CS, CF, data rate)
  • Base and PHY partitioning for portability
  • Subclass 0 operating mode for backward compatibility to JESD204A
  • Subclass 1 and 2 operating modes for deterministic latency support between the ADC/DAC and FPGA
  • Multi-device synchronization
  • Serial lane alignment and monitoring 
  • Ability to tune latency in IP core 
  • Transceiver channel sharing for trasmitter (TX) and receiver (RX) to optimize transceiver count 
  • Hardware-validated design examples that include transport layer design
