JESD204B/C Transmitter IP

Design IP

Overview

SmartDV’s JESD204B/C Transmitter IP is a silicon-proven solution engineered for high-speed serial communication between logic devices and data converters in systems demanding precision and performance. Compliant with both JESD204B and JESD204C standards, it enables scalable, low-latency, and efficient data transmission across multiple lanes and high data rates.

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. The IP supports key features such as lane alignment, deterministic latency, multi-lane synchronization, and subclass support, making it an ideal choice for applications in wireless infrastructure, industrial automation, and high-speed instrumentation.

Benefits

High-Speed Data Transmission – Supports JESD204B and JESD204C standards for deterministic, low-latency serial data transfer up to 12.5 Gbps per lane with programmable clock frequency up to 12.5 GHz.
Scalable Lane Configuration – Configurable 1–8 lanes with selectable SerDes interface widths (10/20/40/60 bits and custom per lane), allowing flexible bandwidth and power trade-offs.
Comprehensive Link Control – Supports Subclass 0/1/2 (JESD204B) and Subclass 1 (JESD204C) operation modes, including frame/multiframe generation, lane alignment, deterministic latency, and HD-mode operation.
Flexible Converter Mapping – Programmable 1–64 converters per transmitter, 1–8 samples per converter, 1–32 frames per multiframe, and frame sizes of 1/2/4/8/16 octets, supporting diverse ADC/DAC data structures.
Precision Data Formatting – Supports 1–32 bit data widths per converter and standard 4/8/12/16/20/24/28/32-bit samples, with CF = 0 or 1 control words and 0–3 control bits per sample for complete JESD compliance.
Identification & Monitoring – Programmable Bank ID (0–15), Device ID (0–255), and Lane ID (0–7) with built-in status registers and error reporting for real-time link diagnostics.
Line Coding & Scrambling – Integrated 8b/10b encoder (JESD204B) and optional data scrambler (JESD204C) ensure DC balance and EMI-optimized signaling performance.
Optimized for SoC Integration – Seamlessly interfaces with AXI-Stream or parallel data sources, providing configurable framing, transport layer control, and deterministic link initialization.

Compliance and Compatibility

Fully compliant with JEDEC JESD204B (including Versions A/B and Subclass 0/1/2) and JESD204C specifications
