SY89547LMG Datasheet PDF - Micrel

●The SY89547LMG is a 3.3V 3.2Gbps differential 4:1 LVDS Multiplexer with 1:2 fanout and internal termination. It provides two copies of the selected input. It features high speed LVDS (350mV) compatible outputs with a guaranteed throughput of up to 3.2Gbps over temperature and voltage. The SY89547L differential inputs include Micrel"s unique, 3-pin internal termination design that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards, both AC- and DC-coupled without external resistor-bias and termination networks. The result is a clean, stub-free, low jitter interface solution. It operates from a single 3.3V supply and is guaranteed over the full industrial temperature range.
