The M21262 is a CDR/reclocker with 4:1 input multiplexer for telecom, datacom, and HD/SD video applications. Each output
channel has an independent multi-rate CDR capable of operating at data rates between 42 Mbps and 3.2 Gbps.
The M21262 can be controlled either through hardwired pins or through a serial programming interface. The hardwired mode
eliminates the need for an external microcontroller to configure the device. The serial programming interface allows complete
control of the device and is available as a two-wire or a four-wire interface.
The M21262 device supports JTAG external boundary scan, which includes all of the high-speed I/O as well as the traditional
digital I/O.
