The PLL502-30 is a monolithic low jitter and low
phase noise VCXO IC with LVCMOS, LVDS and
LVPECL output capabilities, covering the 750kHz to
800MHz output range. It allows the control of the
output frequency with an input voltage (VCON),
using a low cost 12MHz to 25MHz crystal.
This one IC can be used to produce a VCXO with
output frequencies ranging from F XIN / 16 to F XIN x 32
thanks to the four frequency selector pads. This
makes the PLL502-30 ideal as a universal die for
applications ranging from ADSL to SONET.

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied. Operating Temperature is guaranteed by design for all parts

Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at
nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This
however may reduce the pull range.
