AD8123ACPZ-R7集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

AD8123ACPZ-R7屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8123ACPZ-R7驅(qū)動(dòng)器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過(guò)延長(zhǎng)電纜或印制線進(jìn)行通信。確切的功能會(huì)因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。

GENERAL DESCRIPTION

The AD8123 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry inside the AD8123 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 long cable equalization (up to 300 meters). Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.
