ICS309 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.
