Product Description
PCS3P6200A 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.
PCS3P6200A reduces electromagnetic interference
(EMI) at the clock source, allowing system wide reduction
of EMI of all clock dependent signals. PCS3P6200A
allows significant system cost savings by reducing the
number of circuit board layers, ferrite beads, shielding
that are traditionally required to pass EMI regulations.
The Supply Voltage of the Device is 3.3V/2.5V. It has two
Spread Selection Pins, SS1% and SS2% to select among
the four possible deviation options. The Frequency
Deviation across the Frequency range remains within
±10% of the selected deviation. Refer to the Frequency
Deviation Selection Table for details. The Device is
available in a 6L-TSOT23 Package.
Application
PCS3P6200A is targeted for use in a broad range of
applications including Liquid Crystal and Plasma
Displays.
