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.
