Built on three generations of industry-leading crosspoint switches, the M21100 is a high-performance 4x4 crosspoint

switch with signal conditioning, optimized for multilane telecom and datacom applications. Each channel operates in-

dependently at data rates of up to 3.2 Gbps, allowing maximum flexibility in system design. Signal conditioning features

include input equalization and output pre-emphasis, allowing robust reception and transmission of signals to other

devices up to 60” away. User-selectable input interface types allow DC-coupled input to CML, LVDS, and LVPECL. The

outputs can also be DC-coupled to CML and LVDS. The device can be controlled either through hardwired pins or an I2C

compatible interface. The hardwired mode eliminates the need for an external microcontroller, while allowing control of

the key features of the device. The I2C compatible interface allows complete control of the device features.
