Features
Description
The PT7C4502 is a high performance frequency
•
•
•
•
•
•
•
•
•
•
Low cost frequency multiplier
multiplier, which integrates Analog Phase Lock Loop
techniques.
Zero ppm multiplication error
Input crystal frequency of 5 - 30 MHz
Input clock frequency of 4 - 50 MHz
Output clock frequencies up to 180 MHz
Period jitter 50ps (100~180MHz)
Duty cycle of 45/55%
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)
Operating voltages of 3.0 to 5.5V
Tri-state output for board level testing

Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
