ICS1493-17 Datasheet Clock Synthesizer

Manufacturer: Renesas

Overview: PRELIMINARY DATASHEET CLOCK SYNTHESIZER FOR PORTABLE SYSTEMS.

General 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.

Key Features

  • 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.
