ICS1493-17

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS1493-17. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

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 ICS1493-17 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.
