General Description
The SY89231U is a precision, low jitter 3.2GHz
÷3,
÷5 clock divider with a LVDS output. The differential
input
includes
Micrel’s
unique,
3-pin
internal
termination architecture that allows the input 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
outputs
are
325mV,
100K-
compatible LVDS with fast rise/fall times guaranteed
to be less than 200ps.
The SY89231U operates from a 2.5V ±5% supply
and
is
guaranteed
over
the
full
industrial
temperature
range
of
–40°C
to
+85°C.
The
SY89231U is part of Micrel’s high-speed, Precision
Edge
product line.
