ICS300

ICS300/ICS301/ICS302 QTClock™ Quick Turn Clock Synthesizer Description The ICS300 and ICS301 QTClocks™ generate a high quality, high frequency clock output and a reference from a low frequency crystal or clock input. They are designed to replace crystals and crystal oscillators in most electronic systems. The ICS302 can accept a higher frequency clock input to generate up to 200 MHz. The devices contain a One Time Programmable (OTP) ROM which is factory programmed with the PLL divider values to output a broad range of frequencies, from 6 to 200 MHz, allowing customer requests for different frequencies to be shipped in 1-3 days. Using Phase-Locked-Loop (PLL) techniques, the devices run from a standard fundamental mode, inexpensive crystal, or clock. They are smaller and less expensive than one oscillator. Features Packaged as 8 pin SOIC Quick turn frequency programming allows samples in one to three days Replaces nearly any crystal or oscillator ICS300 produces up to 100 MHz at 3.3V, ICS301 produces up to 200 MHz at 3.3V ICS302 accepts up to 125 MHz clock input Easy to cascade with ICS5xx series Input crystal frequency of 5 - 27 MHz Input clock frequency of 2 - 125 MHz Low jitter - 50 ps one sigma Compatible with all popular CPUs Duty cycle of 45/55 Operating voltages of 3.0 to 5.5V Full CMOS level outputs with 25mA drive capability at TTL levels Tri-state output + PLL power down pin Advanced, low power CMOS process Block Diagram VDD GND Crystal ...
