ICS544-01

Clock Divider

Description

Features

The ICS544-01 is crystal oscillator module IC with

divide by 512 frequency output. It employs a 16.777216

MHz fundamental frequency crystal source oscillator to

generate 32.768 kHz output crystal oscillator output. In

addition a divide by 256, 64 and 32 options also

provided through select pins. The chip has an OE pin

that tri-states the output and stops the oscillator

circuits.

• Packaged in 8-pin SOIC or die

• Available in Pb-free package

• ICS’ lowest cost clock divider

• Easy to use with other generators and buffers

• Input clock frequency up to 156 MHz

• Output clock duty cycle of 45/55

• Output Enable

• Advanced, low-power CMOS process

• Operating voltage of 2.25 V to 3.6 V

• Does not degrade phase noise - no PLL

• Available in industrial temperature range

The ICS544-01 is a member of ICS’ ClockBlocks^TM

family of clock building blocks. See the ICS541 and

ICS542 for other clock dividers, and the ICS501, 502,

511, 512, and 525 for clock multipliers.
