P3P8163A
3.3V, LVCMOS Spread
Spectrum Peak EMI
Reduction Device
Product Description
P3P8163A is a 3.3 V, spread spectrum frequency modulator that
generates a 1x, LVCMOS low EMI spread spectrum clock and two
reference clock outputs.
The P3P8163A reduces electromagnetic interference (EMI) at the
clock source, allowing system wide reduction of EMI of down stream
clock and data dependent signals. It allows significant system cost
savings by reducing the number of circuit board layers, ferrite beads,
shielding, and other passive components that are traditionally required
to pass EMI regulations.
The P3P8163A can generate an EMI reduced clock from a
fundamental Crystal or from an external reference clock.
P3P8163A has a SEL pin to turn off CLK2 when ‘1’.
Refer Output Table.
P3P8163A operates over 3.3 V ±5% supply voltage range and is
available in 8 pin SOIC package.
