Product Description

The P2384A is a versatile frequency multiplier that is

designed specifically as cost effective alternative to the

high precision frequency oscillator.

The P2384A can generate a 4X output clock of the input

frequency that allows system cost savings by using an

inexpensive crystal or resonator to achieve high frequency

multiplication.

The P2384A provides up to 312 MHz output clock

frequency through the use of the Phase-Lock-Loop (PLL)

technique which delivers low jitter and high precision

synthesized clocks.

Applications

The P2384A is targeted towards the high frequency CAN

OSC replacement market.

Applications include xDSL,

routers, networking, PC peripherals, and embedded

systems.
