SY58609U数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The SY58609U is a 2.5/3.3V, high-speed, fully differential CML 2:1 MUX capable of processing clock signals up to 2.5GHz and data patterns up to 4.25Gbps. The SY58609U is optimized to provide a buffered output of the selected input with less than 20ps of skew and less than 10psPP total jitter.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) as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an integrated reference voltage (VREF-AC) is provided to bias the VT pin. The outputs are 400mV CML, with extremely fast rise/fall times guaranteed to be less than 90ps.The SY58609U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require LVPECL or LVDS outputs, consider Micrel's SY58610U and SY58611U, 2:1 MUX with 800mV and 325mV output swings, respectively. The SY58609U is part of Micrel's high-speed, Precision Edge® product line.

简介

SY58609U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SY58609U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。
