AD8128ACPZ-R7集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

AD8128ACPZ-R7屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD8128ACPZ-R7驅(qū)動器，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，以通過延長電纜或印制線進行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

GENERAL DESCRIPTION

The AD8128 is a high speed, differential receiver/equalizer that compensates for the transmission losses of unshielded twisted pair (UTP) CAT-5 cables. Various frequency dependent gain stages are summed together to best approximate the inverse frequency response of CAT-5/CAT-5e cable. An equalized bandwidth of 120 MHz can be achieved for 100 meters of cable.

The AD8128 can be used as a standalone receiver/equalizer or in conjunction with the AD8143, triple differential receiver, to provide a complete low cost solution for receiving RGB over UTP cable in such applications as KVM.

The AD8128 has three control pins for optimal CAT-5/CAT-5e compensation. The equalized cable length is directly proportional to the voltage applied to the VPEAKpin, which controls the amount of high frequency peaking. VGAIN adjusts the broadband gain from 0 dB to 3 dB, compensating for the resistive cable loss. VOFFSET allows the output to be shifted by ±2.5 V, adding flexibility for dc-coupled systems.
