General
The PT7C4501/4501A is a high performance frequency
multiplier, which integrates Analog Phase Lock Loop
techniques.
The PT7C4501/4501A 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)
