ICS421-05

www.DataSheet4U.com ICS421-05 DIGITAL VIDEO CAMERA CLOCK Features Ultra-low operating voltage from 1.8 V to 2.4 V 10 mA supply current 27 MHz input clock frequency Fixed 24.576 MHz clock supports IEEE1394 Fixed 12 MHz clock supports USB Fixed 72 MHz CCD clock Packaged in 8-pin TSSOP (Pb free) Description The ICS421-05 is a low-power, low-jitter clock synthesizer developed for digital camera applications. The device accepts a 27 MHz input clock to support common digital video camera interface frequencies including a 12 MHz for USB, 24.576 MHz for IEEE1394, and a 72 MHz CCD clock. Power consumption was minimized by lowering the voltage requirement to 1.8 V minimum. The ICS421-05 utilizes a small form factor 8-pin TSSOP package. ICS is a leader in low power, consumer application clock sources. Devices are capable of supporting CCD, video, audio, USB, CPU, and other peripherals.
