MICROCHIP SY89543LMG-TR

The SY89543L includes two precision, high - speed 2:1 differential Muxes with LVDS (350mV) compatible outputs with a guaranteed data rate throughput of 3.2Gbps over temperature and voltage. The SY89543L differential inputs include a unique, 3 - pin internal termination 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. The SY89543L operates from a single 3.3V supply, and is guaranteed over the full industrial temperature range (-40℃ to +85℃).
