JESD204 technology

Encoding for SerDes synchronization, clock recovery and DC balance

Get started

What is JESD204?

JESD204 technology is a standardized serial interface between data converters (ADCs and DACs) and logic devices (FPGAs or ASICs) which uses encoding for SerDes synchronization, clock recovery and DC balance. Our JESD-compliant products and designs help you significantly improve the performance of high-density systems across a variety of application areas. We provide devices that support both JESD204B and JESD204C.

Learning the differences of JESD204B and JESD204C

This white paper explains the differences between JESD204B and JESD204C standards and the impact those changes have on engineers working on high-speed data converter board designs.

The benefits of TI’s JESD204 IP

checkmark

Lower system cost

Free IP, compared to paying Xilinx for using their IP for this function—no-cost for use with TI converters.

checkmark

Accelerate design time

TI will help you configure the IP for your exact mode. You don’t have to become a JESD204 expert. We handle that knowledge for you.

checkmark

Flexible/easy to use

Requires fewer FPGA resources—pre-configurable and optimizable firmware specifically for your FPGA platform, data converter and JESD204 mode.

JESD204 Rapid Design IP para FPGA conectadas a convertidores de datos de alta velocidad TI

The JESD204 rapid design IP has been designed to enable FPGA engineers to achieve an accelerated path to a working JESD204 system. The IP has been architected in a way that downstream digital processing and other application logic are isolated from most of the performance- and timing-critical (...)
