ICS421-05
DIGITAL VIDEO CAMERA CLOCK
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.
