AD8158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

AD8158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AD8158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 AD8158 is an asynchronous, protocol-agnostic, quad-lane 2:1 switch with a total of 12 differential CML inputs and 12 differential CML outputs. The signal path supports NRZ signaling with data rates up to 6.5 Gbps per lane. Each lane offers programmable receive equalization, programmable output pre-emphasis, programmable output levels, and loss-of signal detection.
