SY89809L
3.3V 1:9 High-Performance, Low-Voltage
Bus Clock Driver
General Description
The SY89809L is a High-Performance Bus Clock Driver
with 9 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 SY89809L 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 SY89809L is available in a
single space saving package, enabling a lower overall cost
solution.
