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.
