PCS3P7101A
Low Power Peak EMI Reducing clock synthesizer
www.DataSheet4U.com
Features
Product Description
• Generates a 4x low EMI clock at the output
• Input frequency: 25 MHz
• Integrated loop filter components.
• Frequency deviation: ±0.25% (Typ) center spread
• Operates with a 3.3V Supply.
• Low power CMOS design.
• Available in 8-pin SOIC package.
• Pin compatible with ICS 341-22
The PCS3P7101A is a low cost, single-output, clock
synthesizer. The PCS3P7101A generates a 4x output clock
from a 25 MHz standard fundamental mode, inexpensive
crystal, or clock. It can replace multiple crystals and
oscillators, saving valuable board space and cost. The
device employs Spread Spectrum technique to reduce
system electro-magnetic interference (EMI).
The device also has a power-down feature that tri-state the
clock output and turns off the PLL when the PD pin is taken
low.
