JESD204C IP

High-Speed Data Converters on Speedster7t FPGAs

As demand for high-speed data converters (ADCs and DACs) continues to grow across various applications such as 5G wireless, aerospace and defense, medical imaging and test and measurement, designers need scalable, efficient, and deterministic data interfaces. To address these needs, the JESD204 interface standard was created — a high-speed serial communications standard that connects data converters to logic devices such as FPGAs, largely replacing older, bulky parallel LVDS interfaces used in the past. JESD204 gain widespread acceptable with the B revision and has since been upgraded with the release of C revision. JESD204C enables higher bandwidth, lower latency, and improved link efficiency when compared to JESD204B.

Achronix offers a high-performance JESD204C IP core for Speedster®7t FPGAs, optimized for high-performance ADC and DAC interfaces while maintaining full backward compatibility with JESD204B.

High-Performance JESD204C IP for Modern Converter Systems

The Achronix JESD204C IP core is designed for high-speed serial data links and supports:

  • Up to 32 Gbps per lane for high-bandwidth converter applications
  • Up to 8 lanes per link for scalable throughput
  • 64b/66b encoding (JESD204C) or 8b/10b encoding (JESD204B)
  • Forward error correction (FEC) for improved link reliability
  • Deterministic latency with system reference (SYSREF) support

These capabilities make the core ideal for high-speed ADC/DAC interfaces, RF transceivers, and data acquisition platforms.

Backward Compatibility with JESD204B

Designers can seamlessly integrate legacy systems thanks to JESD204B backward compatibility. The IP supports both encoding schemes, enabling:

  • Smooth system migration from JESD204B to JESD204C
  • Mixed-generation converter support
  • Reduced development risk

Why Speedster7t FPGAs Are Ideal for JESD204 Designs

The combination of Achronix JESD204C IP with the Speedster7t FPGA architecture creates a powerful platform for high-speed converter systems.

2D Network-on-Chip for Data Movement

Unlike traditional FPGA architectures, Speedster7t features a 2D network-on-chip (NoC) that enables:

  • High-bandwidth, low-latency data transport
  • Efficient movement of JESD204 data streams across the device
  • Reduced routing congestion and power consumption

These capabilities are critical for multi-channel JESD204 systems where data must be distributed quickly and efficiently.

Machine Learning Processors for Real-Time Processing

Integrated machine learning processors (MLPs) allow designers to:

  • Perform real-time data analytics on converter outputs
  • Implement DSP, filtering, and AI-based signal processing
  • Reduce external processing requirements
