P2084A Overview

Low Cost Frequency Multiplier

P2084A
Low Cost Frequency Multiplier
Features
Generates 4x clock of the input clock frequency
Input clock frequency: 3MHz to 78MHz
Output clock frequency:12MHz to 312MHz
External loop filter
Low Cycle-to-Cycle Jitter
3.3V operating voltage range
10mA output drives
TTL or CMOS compatible outputs
Ultra-low power CMOS design
Available in 8-pin SOIC
The P2084A can generate a 4x output clock of the input
frequency which allows system cost savings by using an
inexpensive crystal or resonator to achieve high frequency
multiplication.
The P2084A provides up to 312MHz output clock
frequencies respectively through the use of the Phase-
Lock-Loop (PLL) technique which delivers low jitter and
high precision synthesized clocks.
Applications
The P2084A is targeted towards the high frequency CAN
OSC replacement market. Applications include xDSL,
routers, networking, PC peripherals, and embedded
systems.
Product Description
P2084A is a versatile frequency multiplier that is designed
specifically as cost effective alternatives to the high
precision frequency oscillator.
