GENERAL DESCRIPTION

The ICS8701I is a low skew, ÷1, ÷2 Clock Generator. The low impedance LVCMOS outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 20 to 40 by utilizing the ability of the outputs to drive two series terminated lines.

FEATURES

• 20 LVCMOS outputs, 7W typical output impedance

• Output frequency up to 250MHz

• 200ps bank skew, 250ps output skew, 300ps multiple

frequency skew, 600ps part-to-part skew

• LVCMOS / LVTTL clock input

• LVCMOS control inputs

• Bank enable logic allows unused banks to be disabled

in reduced fanout applications

• 3.3V or mixed 3.3V input, 2.5V output operating

supply modes

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

package body, 0.5mm package lead pitch

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

• Other divide values available on request
