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.
• Extremely low operating current (11 mA)
• Packaged in 20-pin QFN (Pb-free)
• Input crystal or clock frequency of 27 MHz
• Output reference frequency of 27 MHz
• Fixed output frequencies of 37 MHz, 48 MHz and
22.5792 MHz
• Selectable output frequency of either 22.5792 MHz
or 24.576 MHz
• Configurable spread spectrum on 37 MHz output
• Operating core voltage of 1.8 V
• Output voltage of 1.8 V or 2.5 V
• Advanced, low-power CMOS process
