SY89827L

Micrel, Inc.

3.3V 500MHz DUAL 1:10 HSTL FANOUT

Precision Edge

SY89827L

BUFFER/TRANSLATOR WITH 2:1 MUX INPUT

FEATURES

■ Dual LVPECL or HSTL input, 10 differential 1.5V

HSTL compatible outputs

Precision Edge

■ Configurable as dual-channel 10 output or a single-

channel 20 output clock driver

DESCRIPTION

■ Guaranteed AC parameters over temperature and

voltage:

• > 500MHz f

• < 50ps within device skew

• < 1.5ns propagation delay

• < 700ps t / t time

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.

MAX

■ Low jitter design

• < 1ps cycle-to-cycle jitter

RMS

• < 10ps total jitter

■ 3.3V core supply, 1.8V output supply

APPLICATIONS

■ High-performance PCs

■ Workstations

■ Parallel processor-based systems

■ Other high-performance computing

■ Communications
