The PT7C4511 is a high-performance frequency multiplier that integrates Analog Phase Lock Loop techniques.
The PT7C4511 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 200MHz.
The PT7C4511 is a high-performance frequency multiplier, 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).
