Packages.
Description
The PI6C3503 is a Low Power Frequency Multiplier with
Spread Spectrum function to reduce EMI interference. The
PI6C3503 provides a 1 time Spread Spectrum modulated output
from a single clock source or a crystal. The PI6C3503 can
reduce EMI at the clock output and it allows significant system
cost savings by reducing the number of circuit board layers
ferrite beads and shielding that are traditionally required to pass
EMI regulations.
Power down control is selectable through external logic state
setting. The various and small package outlines can save board
size and is easy for layout.
The PI6C3503 can be used in most portable devices with low
power requirements like PDA, DSC, MFP, Media player,
portable-TV, and LCM(LCD Panel Module).
PI6C3503 is one of Pericom clock products, if you have
application need with clock input or output not specified here,
please contact with Pericom for further information or custom
clock design.
