Low Cost Frequency Multiplier
Features
Generates 4X clocks of the Input Clock frequency Input clock frequency range from 20 MHz to 78 MHz Provides up to 312 MHz Output Clock frequency External loop filter Low Cycle-to-cycle jitter 3.3 V Operating Voltage TTL or CMOS compatible outputs Ultra-low power CMOS design Available in Commercial and Industrial temperature ranges Available in 8-pin SOIC and TSSOP Packages
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
