描述 Description

The M21262 is a low power, high-performance single port video reclocker with a 4:1 input mux for 3G/HD/SD (42M-3.2G) professional video applications. 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.
