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

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.
