Overview
ICS309 SERIAL PROGRAMMABLE TRIPLE PLL SS VERSACLOCK SYNTHESIZER 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 ...
