PCS3P8504A
General Purpose Peak EMI
Reduction IC
Functional Description
PCS3P8504A is a versatile, 3.3 V Timing--Safe Peak EMI
reduction IC. PCS3P8504A accepts an input clock either from a
fundamental Crystal or from an external reference (AC or DC coupled
to XIN/CLKIN) and locks on to it delivering a 1x modulated clock
output. PCS3P8504A has a SSON pin for enabling and disabling
Spread Spectrum function.
PCS3P8504A has an SSEXTR pin to select different deviations
depending upon the value of an external resistor connected between
SSEXTR and GND. Modulation Rate (MR) control selects one of the
two different Modulation Rates.
PCS3P8504A operates from a 3.3 V supply, and is available in an
8--pin, WDFN(2 mm x 2 mm) package.
