CLOCK DIVIDER DATASHEET ICS544-01 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 are 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 IDT’s 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 • Pb-free package • IDT’s lowest cost clock divider • Easy to use with other generators and buffers • Input crystal at 16.
