AD8156ABCZ集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

AD8156ABCZ属于集成电路（IC）的信号开关多路复用器解码器。由亚德诺半导体技术有限公司制造生产的AD8156ABCZ信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。

GENERAL DESCRIPTION

The AD8156, a member of the Xstream line of products, is a high speed, fully differential, digital crosspoint switch. The part can function as a 4 × 4 crosspoint switch with double-latched memory, allowing simultaneous updates, or as a dual 2 × 2 with direct output control. The AD8156 has low power dissipation, typically 700 mW on 3.3 V with all outputs and input equalizers active. It operates at any data rate from dc to 6.25 Gbps per port.

Each input channel on the AD8156 has a programmable input equalizer to compensate for signal loss over a backplane.
