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 快速設計 IP，適用連接到 TI 高速資料轉換器的 FPGA

JESD204 快速設計 IP 被設計用於幫助 FPGA 工程師快速實現可運作的 JESD204 系統，從而加速開發過程。該 IP 的架構設計使得下游數位處理和其他應用邏輯能夠隔離於 JESD204 通訊協定的大多數性能和時序關鍵約束之外。該 IP 能夠幫助設計人員減少韌體開發時間並簡化 FPGA 的整合。

JESD204 快速設計 IP 無需權利金，用於 TI 高速資料轉換器。TI 將協助使用者配置初始連結，針對特定 FPGA 平台與 TI 資料轉換器 JMODE 之間的使用進行自訂。TI 將在 IP 測試完成並準備部署後，透過安全下載連結提供 IP。
