Clock Synthesizer For Portable Systems

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 27 MHz reference Clock for Video Using IDTs 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. 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 By Integrated Device Technology
