Product Description
PCS3P73U00A is a versatile, 3.3V / 2.5V Peak EMI
reduction IC. PCS3P73U00A accepts an input clock either
from a Crystal or from an external reference (AC or DC
Block Diagram
coupled to XIN / CLKIN) and locks on to it delivering a 1x
modulated clock output. PCS3P73U00A has a Frequency
Selection (FS) control that facilitates selecting one of the
two frequency ranges within the operating frequency range.
Refer to the frequency Selection table for details.
PCS3P73U00A 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 two different Modulation Rates.
PCS3P73U00A operates from a 3.3V / 2.5V supply and is
available in an 8 pin TSSOP, SOIC, and TDFN(2X2) COL
packages, over Commercial temperature range.
Applications
PCS3P73U00A is targeted for USB applications.
Refer to SSEXTR Resistance Table for USB2.0
compliance for commonly used frequencies.
