The PT7C4502 is the most cost effective way to generate a high quality, high frequency clock output from a lower frequency crystal or clock input. It is designed to replace crystal oscillators in most electronic systems, clock multiplier and frequency translation. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 180 MHz. The complex Logic divider is the ability to generate nine different popular multiplication factors, allowing one chip to output many common frequencies. The device also has an Output Enable pin that tri- states the clock output when the OE pin is taken low. This product is intended for clock generation and frequency translation with low output jitter (variation in the output period) Block Diagram PLL Clock Synthesis and Control Circuit Crystal Oscillator S0 S1 X2 CLK V CC GND X1/ICLK Output Buffer |
