描述 Description

The SY54023R is a fully differential, low voltage 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail Safe Inputs. The SY54023R can process clock signals as fast as 2.5GHz or data patterns up to 3.2Gbps.The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled from a 2.5V driver) as small as 100mV (200mVPP) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 95ps.The SY54023R operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY54023R is part of Micrel's high-speed, Precision Edge® product line.

简介

SY54023A属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的SY54023A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。
