The SY89808L is a High-Performance Bus Clock Driver with
9 differential HSTL (High-Speed Transceiver Logic) 1.5V
compatible 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 and triple-buffered
so that the outputs will only be enabled/disabled when they are
already in the LOW state. This avoids any potential of generating
a runt clock pulse when the device is enabled/disabled, as can
occur with an asynchronous control. The triple-buffering feature
provides a three-clock delay from the time the OE input is
asserted/de-asserted to when the clock appears at the outputs.
The SY89808L features an ultra-low pin-to-pin skew of less
than 25ps. The SY89808L is available in a 32-TQFP space
saving package, enabling a lower overall cost solution.
