The MAX3783 is a dual serial multiplexer (mux) and buffer with selectable line-side loopback for system interconnect and serial backplane applications up to 2.7Gbps. Each independent channel consists of a transmitter with fanout of two and a receiver with a 2:1 input mux. Selectable loopback paths support system testing. Operating from a single 3.3V supply, this device has current-mode logic (CML) inputs and outputs, which can be AC-coupled for PECL compatibility, if desired. The IC is packaged in a compact 48-pin TQFP-EP package with exposed pad. Typical power consumption is 1.12W.
