The First True Drop-in Solution
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.
