JESD204D Transmitter IP

Design IP

Overview

SmartDV’s JESD204D Transmitter IP enables high-speed, reliable serial data transmission from logic devices to data converters, tailored for applications in wireless communication, medical imaging, radar, and high-performance data acquisition systems. Fully compliant with the JESD204D standard, it ensures efficient, low-latency communication with robust support for deterministic timing and multi-lane scalability.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. With features like continuous deterministic latency, flexible lane configurations, and support for advanced scrambling and error reporting, it delivers a streamlined path to building next-generation, high-bandwidth systems.

Benefits

Ultra-High-Speed Data Transmission – Supports PAM4 signaling up to 116 Gbps per lane and PAM2 up to 58 Gbps, with programmable clock frequencies up to 116 GHz (PAM4) and 58 GHz (PAM2) for next-generation high-performance data converters.
Scalable Multi-Lane Architecture – Configurable 1 to 8 lanes with selectable SerDes interface widths (10/20/40/60 bits and custom configurations) for scalable throughput and efficient link utilization.
Flexible Converter and Frame Configuration – Supports 1 to 64 converters per transmitter, 1 to 8 samples per converter, and frame sizes of 1/2/4/8/16 octets with 1 to 32 frames per multiframe, delivering complete flexibility across different converter topologies.
Advanced Link Control and Synchronization – Implements Subclasses 0, 1, and 3, providing deterministic latency, lane alignment, and HD-mode operation; includes MCDA-ML (Multiple-Converter Device Alignment, Multiple-Lanes) support for synchronized multi-device operation.
Enhanced FEC and Error Management – Integrates Reed-Solomon Forward Error Correction (RS-FEC) per IEEE 802.3 Clause 91. Provides full FEC encoding/decoding, alignment block, payload block, payload symbols, and FEC codeword handling for robust link reliability.
Comprehensive Data Formatting – Supports 1 to 32-bit data widths per converter, CF = 0 or 1 control words per frame clock, 0 to 3 control bits per sample, and standardized 4/8/12/16/20/24/28/32-bit sample sizes.
Programmable Scrambling and Line Coding – Supports enable/disable scrambler, advanced lane alignment, and compliant block and frame mapping for optimized signal integrity and EMI reduction.
Optimized for SoC Integration – Designed for seamless connection with AXI-Stream or parallel data sources, featuring programmable framing, FEC pipeline configuration, and link monitoring for reliable JESD204D link bring-up.
