Description

The SY89544U 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 SY89544U 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 SY89544U operates from a single 2.5V supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require a 3.3V supply, consider the SY89545L. For applications that require two differential outputs, consider the SY89546U or SY89547L. The SY89544U is part of Micrel's Precision Edge® product family.
