AD8155ACPZ集成電路（IC）的信號開關多路復用器解碼器規(guī)格書PDF中文資料

AD8155ACPZ屬于集成電路（IC）的信號開關多路復用器解碼器。由亞德諾半導體技術有限公司制造生產的AD8155ACPZ信號開關，多路復用器，解碼器邏輯型信號開關、多路復用器和編碼器 IC 可用于對以數字格式表示數據的電信號進行路由和選擇。這些器件與設計用于模擬信號的類似產品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內的無窮變化量。

GENERAL DESCRIPTION

The AD8155 is an asynchronous, protocol-agnostic, dual-lane 2:1 switch with a total of six differential CML inputs and six 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 preemphasis, programmable output levels, and loss-of-signal detection.

The nonblocking switch core of the AD8155 implements a 2:1 multiplexer and 1:2 demultiplexer per lane and supports independent lane switching through the two select pins, SEL[1:0]. Each port is a two-lane link. Every lane implements an asynchronous path supporting dc to 6.5 Gbps NRZ data, fully independent of other lanes. The AD8155 has low latency and very low lane-to-lane skew.
