General Description
The
SY89218U
is
a
2.5V
precision,
high-speed,
integrated clock divider and LVDS fanout buffer capable
of handling clocks up to 1.5GHz. Optimized for
communications applications, the four independently
controlled output banks are phase-matched and can be
configured for pass through (÷1), ÷2 or ÷4 divider ratios.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that allows the user to
interface to any differential signal (AC- or DC-coupled)
as small as 100mV (200mVPP) without any level shifting
or termination resistor networks in the signal path. The
low-skew, low-jitter outputs are LVDS compatible with
extremely fast rise/fall times guaranteed to be less than
200ps.
The /MR (master reset) input asynchronously resets the
outputs. A four-clock delay after de-asserting /MR allows
the counters to synchronize and start the outputs from
the same state without any runt pulse.
The SY89218U is part of Micrel’s Precision Edge
product family. All support documentation can be found
at Micrel's web site at: www.micrel.com.
