The ADC34J2x are a high-linearity, ultra-low power, dual-channel, 12-bit, 50-MSPS to 160-MSPS, analog-to-digital converter (ADC) family. The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. A clock input divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization. The devices support JESD204B interfaces in order to reduce the number of interface lines, thus allowing for high system integration density. The JESD204B interface is a serial interface, where the data of each ADC are serialized and output over only one differential pair. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock by 20 to derive the bit clock that is used to serialize the 12-bit data from each channel. The devices support subclass 1 with interface speeds up to 3.2 Gbps.

TI204C-IP — Request for JESD204 rapid design IP

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。
