PRELIMINARY

ICS83905I

Integrated

Circuit

Systems, Inc.

KEW, 1:6 CRYSTAL

NTERFACE

- -

LVCMOS / LVTTL FANOUT

BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS83905I is a low skew, 1-to-6 LVCMOS / • 6 LVCMOS / LVTTL outputs

ICS

LVTTL Fanout Buffer and a member of the

• Crystal oscillator interface

HiPerClockS™

HiPerClockS™family of High Performance Clock

Solutions from ICS. The ICS83905I single ended

clock input accepts LVCMOS or LVTTL input lev-

els.The low impedance LVCMOS/LVTTL outputs are designed

to drive 50Ω series or parallel terminated transmission lines.

The effective fanout can be increased from 6 to 12 by utilizing

the ability of the outputs to drive two series terminated lines.

• Output frequency range: 10MHz to 50MHz

• Crystal input frequency range: 10MHz to 50MHz

• Output skew: 10ps (typical)

• 5V tolerant enable inputs

• Synchronous output enables

The ICS83905I is characterized at full 3.3V, 2.5V, and 1.8V, mixed

3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply

mode. Guaranteed output and part-to-part skew characteris-

tics along with the 1.8V output capabilities makes the

ICS83905I ideal for high performance, single ended applica-

tions that also require a limited output voltage.

• Operating supply modes: Full 3.3V, 2.5V and 1.8V,

mixed 3.3Vcore/2.5V or1.8V operating supply, and

mixed 2.5V core/1.8V operating supply

• -40°C to 85°C ambient operating temperature

• Pin compatible to MPC905
