The SY89547L is a precision, high-speed 4:1 differential
multiplexer that provides two copies of the selected input.
The high speed LVDS (350mV) compatible outputs with a
guaranteed throughput of up to 3.2Gbps over temperature
and voltage.
The SY89547L differential inputs include Micrel’s unique,
3-pin internal termination design 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 SY89547L 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 SY89546U. For applications that only require
one differential output, consider the SY89544U or SY89545L.
The SY89547L is part of a Micrel’s Precision Edge product
family. All support documentation can be found on Micrel’s
web site at: www.micrel.com.
