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

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

(2mmX2mm) packages, over commercial temperature

range.

Application

PCS3P73U00A is targeted for USB applications. Refer to

SSEXTR Resistance Table for USB2.0 Compliance for

commonly used frequencies.
