MAX3890 - +3.3V、2.5Gbps、SDH/SONET 16:1串行器，带有时钟合成及LVDS输入 - 高速互联(差分信号链路) - 低功耗、低成本收发器芯片组 - 美信半导体

产品概述

The MAX3890 serializer is ideal for converting 16-bit-wide, 155Mbps parallel data to 2.5Gbps serial data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, this device accepts low-voltage differential-signal (LVDS) clock and data inputs for interfacing with high-speed digital circuitry, and delivers PECL serial data and clock outputs. A fully integrated PLL synthesizes an internal 2.5GHz serial clock from a 155.52MHz, 77.76MHz, 51.84MHz, or 38.88MHz reference clock. A loopback data output is provided to facilitate system diagnostic testing.

The MAX3890 is available in the extended temperature range (-40°C to +85°C) in a 64-pin TQFP exposed- paddle (EP) package.
