SY89543L FEATURES
Dual 2:1 multiplexer
Guaranteed AC performance over temp and voltage: DC-to > 3.2Gbps data rate throughput < 510ps In-to-Out tpd Precision EdgeВ® 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 to +85°C). For applications that require a 2.5V supply,
consider the SY89542U. The SY89543L is part of a Micrel’s …
