DESCRIPTION
The SY58051U is an ultra-fast, low jitter universal logic
gate with a guaranteed maximum data or clock throughput
of 10.7Gbps or 7GHz, respectively. This AnyGate^®
differential logic device will produce many logic functions of
two Boolean variables, such as AND, NAND, OR, NOR,
DELAY, or NEGATION.
The SY58051U differential inputs include a unique,
internal termination design that allows access to the
termination network through a V_T 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 differential CML output is
optimized for 50Ω environments with internal 50Ω source
termination and a 400mV output swing.
The SY58051U operates from a 2.5V or 3.3V supply,
and is guaranteed over the full industrial temperature range
(–40°C to +85°C). The SY58051U is part of a Micrel’s
Precision Edge^® product family.
