ICS1493-17 Overview
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)...
