PCS3P6100A is a versatile spread spectrum modulator
designed specifically for a wide range of clock
frequencies. The device addresses the need of a low EMI
clock generator for use in display systems covering wide
choice of pixel frequencies.
PCS3P6100A reduces electromagnetic interference
(EMI) at the clock source, allowing system wide reduction
of EMI of all clock dependent signals. PCS3P6100A
allows significant system cost savings by reducing the
number of circuit board layers, ferrite beads, and
shielding that are traditionally required to pass EMI
The Supply Voltage of the Device is 3.3V / 2.5V. It has
two Spread Selection Pins, SS1% and SS2%. Refer to
the Spread Deviation Selection Table for details. The
Device is available in 6L-TSOT23 Package.
PCS3P6100A is targeted for use in Display Systems.
