M21353

4.25 Gbps Twelve-Channel Backplane Equalizer and Driver with 12x12 Crosspoint Switch

Overview

Description

The M21353 is a twelve channel device designed to enable the transmission of multi-gigabit serial data through the most challenging environments. The device features twelve independent, programmable equalizers that equalize data at rates up to 4.25 Gbps. Control of the M21353 is provided through an I2C compatible software control interface. The M21353 can also self-configure from an external EEPROM without the need for a host processor. For compatibility with PCI-Express and S-ATA/SAS systems, the M21353 is designed with an electrical idle pass-through function to drive the differential output to the common mode level during OOB signaling. Boundary scan is provided for high-speed input and output pins, and the device is available in a 12x12 mm, 88 pin MLF package.
