Microchip | SY89543LMG-TR

The SY89543LMG TR includes two precision, high-speed 2:1 differential Muxes with LVDS (350 mV) compatible outputs with a guaranteed data rate throughput of 3.2 Gbps 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 3.3 V supply, and is guaranteed over the full industrial temperature range (–40°C to +85°C). For applications that require a 2.5 V supply, consider the SY89542U. The SY89543L is part of a Micrel’s Precision Edge® product family.
