AD8124集成電路（IC）的視頻處理規(guī)格書PDF中文資料

AD8124屬于集成電路（IC）的視頻處理。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8124視頻處理一種集成電路 (IC) 半導(dǎo)體器件，設(shè)計(jì)用于在放大、增強(qiáng)、編碼器和解碼器（編解碼器）、緩沖、校準(zhǔn)、處理、信號(hào)調(diào)節(jié)、調(diào)制與解調(diào)、轉(zhuǎn)換、傳輸、伽瑪校正、切換、OSD、數(shù)字化和多路復(fù)用等應(yīng)用中處理音頻和/或視頻信號(hào)。

GENERAL DESCRIPTION

The AD8124 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 200 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry inside the AD8124 controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. This technique optimizes its performance for low noise, short-to-medium range applications, while at the same time provides the high gain bandwidth required for longer cable equalization (up to 200 meters). Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.
