M21151

3.2 Gbps 144x144 Asynchronous Crosspoint Switch

Overview

Description

Highest Performance, Lowest Power Crosspoint Switch Reduces System Cost and Complexity

Built on three generations of industry-leading crosspoint switches, the M21151, designed for today’s demanding telecom and datacom applications, is a low-power CMOS, high-speed 144x144 crosspoint switch with robust signal conditioning circuits for driving and receiving high-speed signals through backplanes.

The device consumes as low as 12 W of power (typical) with all channels operational. In addition, the PowerScaler™ features offer dynamically scalable switch settings to further reduce power consumption.

The signal conditioning features of the M21151 include per channel programmable input equalizer (IE) and output pre-emphasis (PE) circuits. The IE circuit opens the input data eye in applications where long PCB traces and cables are used. The PE provides a boost of the high frequency content of the output signal, such that the data eye remains open after passing through a long interconnect of PCB traces and cables.

The device supports data rates from 0 to 3.2 Gbps on each channel, allowing any combination of SONET, Fibre Channel (1x, 2x, 10x), InfiniBand, Gigabit Ethernet and parallel 10 Gbps Ethernet traffic. For applications that require integrated CDRs, the M21156, 144x144 crosspoint switch with integrated CDRs, input equalization and pre-emphasis can be used.
