M21148
6.5 Gbps 48x48 Asynchronous Crosspoint Switch
Overview
Description
The M21148 is a 48x48 asynchronous fully non-blocking crosspoint switch operating at data rates up to 6.5 Gbps. The M21148 can be configured to switch channels as individual lanes (Lane Mode) or in groups of four (Group Mode). The device includes advanced signal conditioning capabilities that enable the transmission of 6.5 Gbps NRZ data over PCB channels that exceed one meter in length. Signal conditioning circuits counteract frequency dependent impairments in the channel that degrade the signal quality. Specific device capabilities include individual, per-lane programmable input equalization and output de-emphasis. Configuration of the device is done through a set of register writes using one of the integrated 2-wire serial (I2C-compatible), 4-wire serial, or parallel digital interfaces.
