The ICS620-01 is a low cost, low jitter, high performance clock synthesizer for digital still cameras. Using analog Phase-Locked Loop (PLL) techniques, the device uses a 14.318 MHz crystal input to produce multiple output clocks required in the camera. It provides selectable NTSC/PAL clock, a selectable processor clock, a selectable CCD clock, and a selectable interface clocks. Most clocks are generated to a very low ppm synthesis error rate.
