SY89824L

LOW VOLTAGE BUS CLOCK DRIVER

FEATURES

■ 3.3V core supply, 1.8V output supply for reduced

power

Precision Edge

■ LVPECL and HSTL inputs

■ 22 differential HSTL (low-voltage swing) output pairs

DESCRIPTION

■ HSTL outputs drive 50Ω to ground with no offset

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.
