Most Highly Integrated, Highest Performance, Lowest Power Crosspoint Switch Reduces System Cost and Complexity
Built on three generations of industry-leading crosspoint switches, the M21156, designed for today’s demanding telecom and datacom applications, is a low-power CMOS, high-speed 144x144 crosspoint switch with 144 independent CDRs, and robust signal conditioning circuits for driving and receiving high-speed signals through backplanes.
The device consumes as low as 17 W of power (typical) with all channels and CDRs operational. In addition, the PowerScaler™ features offer dynamically scalable switch settings to further reduce power consumption.
Each input has a dedicated high-jitter tolerant, low-jitter generation CDR with internal loop filter, which operates independently at any data rate from 1.0 to 1.6 Gbps, or 2.0 to 3.2 Gbps.
The signal conditioning features of the M21156 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 do not require an integrated CDR, the M21151, 144x144 crosspoint switch with input equalization and pre-emphasis can be used.
