General

The PT7C4511 is a high performance frequency

multiplier, which 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

200 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 tristates

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)
