Clock and Data Distribution -- SY89545L-Image

The SY89545L is a fast, low jitter 4:1 differential MUX with an LVDS (350mV) compatible output with guaranteed data rate throughput of 3.2Gbps over temperature and voltage.The SY89545L 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 SY89545L operates from a single 3.3V supply, and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require a 2.5V supply, consider the SY89544U. For applications that require two differential outputs, consider the SY89546U or SY89545L.The SY89545L is part of a Micrel's Precision Edge® product family.
