Product Description
PCS3P2189A is a versatile spread spectrum frequency
modulator that generates a low EMI 4x clock at the
output. PCS3P2189A offers four
spread
Spread Deviation Selection Tabnle). PCS3P2189A
reduces electromagnetic interference (EMI) at the clock
source, allowing system wide reduction of EMI of
clock
significant system cost savings by reducing the number
of circuit board layers, ferrite beads, and shielding that
are traditionally required to pass EMI regulations.
PCS3P2189A has spread spectrum ON/OFF option.
The PCS3P2189A uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all digital method.
