Functional Description
PCS3P7303A is a versatile, 3.3V/2.5V Peak EMI reduction
IC based on Timing-Safe™ technology. PCS3P7303A
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.
PCS3P7303A 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.
PCS3P7303A 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.
PCS3P7303A operates from a 3.3V/2.5V supply and is
available in an 8-pin TSSOP and 8L 2mmX2mm WDFN
packages.
Application
PCS3P7303A is targeted for many applications including
USB and SATA.
