The SY89827L is a High Performance Bus Clock

Driver with dual 1:10 or single 1:20 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 Enables

(OE1 & OE2) are 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 SY89827L features extremely low skew performance

of <50ps over temperature and voltage –performance

previously unachievable in a standard product having such

a high number of outputs. The SY89827L is available in a

single space saving package, enabling a lower overall cost

solution. For applications that require greater HSTL fanout

capability, consider the SY89824L.
