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
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.
•
Available in 8-pin SOIC and TSSOP Packages
Applications
The P2384A is targeted towards the high frequency CAN
OSC replacement market. Applications include xDSL,
routers, networking, PC peripherals, and embedded
systems.
