The SY89824L is a High Performance Bus Clock Driver
with 22 differential HSTL (High Speed Transceiver Logic)
output pairs. The part is designed for use in low voltage
(3.3V/1.8V) applications which require a large number of
outputs to drive precisely aligned, ultra low skew signals to
their destination. The input is multiplexed from either HSTL
or LVPECL (Low Voltage Positive Emitter Coupled Logic)
by the CLK_SEL pin. The Output Enable (OE) is
synchronous so that the outputs will only be enabled/
disabled when they are already in the LOW state. This
avoids any chance of generating a runt clock pulse when
the device is enabled/disabled as can happen with an
asynchronous control.
The SY89824L features low pin-to-pin skew (50ps max.)
and low part-to-part skew (200ps max.)—performance
previously unachievable in a standard product having such
a high number of outputs. The SY89824L is available in a
single space saving package, enabling a lower overall cost
solution.
