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. T...
