Systems, Inc.

KEW, 1-TO-9

LVCMOS FANOUT

BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS83947I is a low skew, 1-to-9 LVCMOS

• 9 LVCMOS/LVTTL outputs

ICS

Fanout Buffer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

ICS. The low impedance LVCMOS/LVTTL out-

puts are designed to drive 50Ω series or parallel

• Selectable CLK0 and CLK1 can accept the following

input levels:LVCMOS and LVTTL

HiPerClockS™

• Maximum output frequency: 110MHz

• Output skew: 500ps (maximum)

• Part-to-part skew: 2ns (maximum)

• 3.3V operating supply

terminated transmission lines.The effective fanout can be in-

creased from 9 to 18 by utilizing the ability of the outputs to

drive two series terminated lines.

Guaranteed output and part-to-part skew characteristics

make the ICS83947I ideal for high performance, single ended

applications that also require a limited output voltage.

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

• Lead-Free package available

• Pin compatible with the MPC947
