Description
The ICS1493-17 is a low-power, low-jitter clock synthesizer designed to replace multiple crystals and oscillators in portable audio/video systems. The device generates a 37 MHz processor clock, a 48 MHz USB clock, a fixed 22.5792 MHz audio clock, a selectable 24.576 MHz or 22.5792 MHz audio clock, and a 27MHz reference clock for video. Using ICS’ proprietary mix of analog and digital Phase-Locked Loop (PLL) technology, the device spreads the frequency spectrum of the 37 MHz output, reducing the peak amplitude of by up to 16 dB. An output enable (OE) pin lowers the chip power consumption while tri-stating all outputs.
