The AFE2256 is a 256-channel, analog front-end (AFE) designed to suit the requirements of flat-panel detector (FPD) based digital x-ray systems. The device includes 256 integrators, a programmable gain amplifier (PGA) for full-scale charge level selection, a correlated double sampler with dual banking, and 256:4 analog multiplexers.

The device also features four 16-bit successive-approximation register (SAR) analog-to-digital converters (ADCs). Serial data from the ADCs are available in low-voltage differential signaling (LVDS) format.

The nap and power-down modes enable substantial power savings, and are especially useful in battery-powered systems.

AFE2256EVM — 適用於數位 X 光平板偵測器的 AFE2256 256 通道 AFE 評估模組

AFE2256EVM 是一款基於 USB 的緊湊型評估套件，用於評估 256 通道類比前端 AFE2256 COF。此 EVM 是獨立的，具有板載 DAC 和發電功能，大大減少了對外部設備的依賴。該套件由一個 EVM、兩個單獨的 COF 轉接器以及易於使用的軟體組成，可用於評估 COF 裝置的性能。COF 轉接器為可拆式，因此可以使用單一 EVM 設定來評估多個 COF 轉接器。USB 2.0 介面透過微控制器提供快速配置下載和 FPGA-PC 通訊。
