Product Description
The P2082A and P2084A are versatile frequency
Block Diagram
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.
