SY58029U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 SY58029U is a 2.5V/3.3V precision, high-speed, 4:1 differential multiplexer with 100k LVPECL (800mV) compatible outputs, capable of handling clocks up to 4GHz and data streams up to 5Gbps. In addition, a 1:2 fanout buffer provides two copies of the selected inputs.The differential input includes Micrel's unique, 3-pin input termination architecture that allows customers to interface to any differential signal (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The result is a clean, stub-free, low-jitter interface solution. The outputs are 800mV LVPECL, (100k temperature compensated) with extremely fast rise/ fall times guaranteed to be less than 110ps.The SY58029U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. For applications that require CML outputs, consider the SY58028U. For 400mV LVPECL outputs, consider the SY58030U. The SY58029U is part of Micrel's high-speed, Precision Edge®product line.

简介

SY58029U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SY58029U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。
