LOW SKEW, 1-TO-24

DIFFERENTIAL-TO-LVCMOS FANOUT BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS8344 is a low voltage, low skew fanout

• 24 LVCMOS outputs, 7Ω typical output impedance

,&6

buffer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

ICS. The ICS8344 is designed to translate any

differential signal levels to LVCMOS levels. The

• Output frequency up to 167MHz

HiPerClockS™

• 275ps output skew, 600ps part to part skew

• Translates any differential input signal (PECL, HSTL, LVDS)

to LVCMOS without external bias networks

low impedance LVCMOS outputs are designed to drive 50Ω

series or parallel terminated transmission lines. The effective

fanout can be increased to 48 by utilizing the ability of the

outputs to drive two series terminated lines. Redundant clock

applications can make use of the dual clock input. The dual

clock inputs also facilitate board level testing. ICS8344 is

characterized at full 3.3V, full 2.5V and mixed 3.3V input and

2.5V output operating supply modes.

• Translates any single-ended input signal to LVCMOS with

resistor bias on nCLK input

• Translates and inverts any single-ended input signal to

LVCMOS with resistor bias on CLK input

• Multiple differential clock input pairs for redundant clock

applications

Guaranteed output and part-to-part skew characteristics

make the ICS8344 ideal for those clock distribution applica-

tions demanding well defined performance and repeatability.

• LVCMOS control inputs

• Multiple output enable pins for disabling unused outputs in

reduced fanout applications

• 3.3V, 2.5V or mixed 3.3V, 2.5V operating supply modes

• 48 lead low-profile QFP(LQFP), 7mm x 7mm x 1.4mm

package body, 0.5mm package lead pitch

• 0°C to 70°C ambient operating temperature

• Industrial temperature versions available upon request
