DATASHEET

SERIAL PROGRAMMABLE TRIPLE PLL SS VERSACLOCK SYNTH

Description

The ICS309 is a versatile serially-programmable, triple

PLL with spread spectrum clock source. The ICS309

can generate any frequency from 250kHz to 200 MHz,

and up to 6 different output frequencies simultaneously.

The outputs can be reprogrammed on-the-fly, and will

lock to a new frequency in 10 ms or less.

To reduce system EMI emissions, spread spectrum is

available that supports modulation frequencies of

31 kHz and 120 kHz, as well as modulation amplitudes

of +/-0.25% to +/-2.0%. Both center and down-spread

options are available.

The device includes a PDTS pin which tri-states the

output clocks and powers down the entire chip.

The ICS309 default for non-programmed start-up are

buffered reference clock outputs on all clock output

pins.

IDT’s VersaClock programming software allows the

user to configure up to 9 outputs with target

frequencies, spread spectrum capabilities or buffered

reference clock outputs. The VersaClock

software

automatically configures the PLLs for optimal overall

performance.
