DESCRIPTION
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°C t...
