P2082A

P2084A

multipliers that are designed specifically as cost effective

alternatives to the high precision frequency oscillator.

The P2082A/84A can generate a 2X and 4X output clock

respectively of the input frequency which allows system

cost savings by using an inexpensive crystal or resonator

to achieve high frequency multiplication.

The P2082A/84A provides up to 156 MHz and 312 MHz

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 P2082A/84A is targeted towards the high frequency

CAN OSC replacement market. Applications include xDSL,

routers, networking, PC peripherals, and embedded

systems.
