Features
from a lower frequency crystal or clock input. It is
designed to replace crystal oscillators in most electronic
• Zero ppm multiplication error
systems, clock multiplier and frequency translation.
• Input crystal frequency of 5 - 30 MHz
• Input clock frequency of 4 - 50 MHz
Using Phase-Locked-Loop (PLL) techniques, the
• Output clock frequencies up to 200 MHz
device uses a standard fundamental mode,
• Peak to Peak Jitter less than 200ps over 200ns interval
inexpensive crystal to produce output clocks up to
(100~200MHz)
200 MHz.
• Period jitter less than 100ps(70~200MHz)
The complex Logic divider is the ability to generate
• Duty cycle of 45/55% up to 120 MHz at +3.3V and
nine different popular multiplication factors, allowing
150MHz at +5V
one chip to output many common frequencies.
• 9 selectable frequencies controlled by S0, S1 pins
• Operating voltages of 3.0 to 5.5V
The device also has an Output Enable pin that tri-
• Tri-state output for board level testing
states the clock output when the OE pin is taken low.
This product is intended for clock generation and
