M21450G-15 MACOM

M21450 6.5 Gbps Dual-Channel Backplane Driver and Adaptive Equalizer with 2x2 Crosspoint Switch The M21450 is a dual channel device designed to enable the transmission of multi gigabit serial data through the most challenging environments. The device features two independent adaptive equalizers that automatically equalize data at rates up to 6.5 Gbps. Control of key functions of the M21450 is provided through hardware pins, 2 and full register control of the M21450 is provided through an I C compatible software control interface. The M21450 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 M21450 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 through a JTAG port, and the device is available in a 6x6 mm, 40-pin, QFN package.
