P2384A
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.
systems.
Applications include xDSL,
routers, networking, PC peripherals, and embedded
