SY89852U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 SY89852U is a 2.5V/3.3V precision, high-speed, 2:1 differential MUX capable of handling clocks up to 2.5GHz and data streams up to 2.5Gbps.The differential input includes Micrel's unique, patent pending 3-pin input termination architecture that allows users to interface to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The unique, patent input isolation design minimizes crosstalk minimizing crosstalk induced jitter. The outputs are 800mV LVPECL, with extremely fast rise/fall time guaranteed to be less than 180ps.The SY89852U 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. The SY89852U is part of Micrel's high-speed, Precision Edge® product line.

简介

SY89852U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SY89852U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。
