PRELIMINARY INFORMATION
ICS544-01
Clock Divider
Description
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.
The ICS544-01 is a member of ICS’ ClockBlocksTM
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.
Features
• 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
