The MAX3781 is a 2.75Gbps dual multiplexer (mux) and buffer. Each half of the MAX3781 has a transmitter with a fanout of two and a receiver with a 2:1 mux.
Operating from a single +3.3V supply, this device accepts CML or AC-coupled PECL inputs and provides CML outputs. The outputs can be AC-coupled for compatibility with PECL inputs if needed. The MAX3781 is packaged in a compact 48-pin 7x7mm TQFP exposed-paddle package and typically consumes 1.2W power. A power-saving mode disables the unused buffer output and reduces typical power to 0.9W.
Applications
- 2.75Gbps Serial Communications
- Serial Backplane Redundancy
- System Interconnect Redundancy
