The ADS528x is a family of high-performance, low-power, octal channel analog-to-digital converters (ADCs). Available in either a 9mm × 9mm QFN package or an HTQFP-80 package, with serialized low-voltage differential signaling (LVDS) outputs and a wide variety of programmable features, the ADS528x is highly customizable for a diversity of applications and offers an unprecedented level of system integration. An application note, XAPP774 (available at www.xilinx.com), describes how to interface the serial LVDS outputs of TI&3146;s ADCs to Xilinx field-programmable gate arrays (FPGAs). The ADS528x family is specified over the industrial temperature range of –40°C to +85°C.

ADS5281EVM — ADS5281 八通道、12 位元、50-MSPS 類比轉數位轉換器評估模組電路板

特別說明:客戶若想評估 ADS528x,應訂購 ADS528xEVM、ADSDeSer-50EVM 及 ADSDESER-50EVM 轉接卡。

ADS5281EVM 提供了一個平台,可評估各種訊號、參考和電源條件下的八通道 ADS5281 類比轉數位轉換器 (ADC)。

EVM 提供了一個外部 SMA 連接器,用於連接八個類比輸入到 ADC 和 ADC 時鐘的輸入。ADC 可以使用單端時鐘或差動時鐘計時、並在 EVM 上佈建,讓使用者能使用單端 PECL 時鐘或差動變壓器耦合時鐘來評估 ADC。

EVM 透過高速、高密度 Samtec 輸出接頭提供數位輸出。數位輸出連接器直接與 TSW1200 (...)
