FEATURES
Integrated voltage-controlled crystal oscillator
circuitry (VCXO) (pull range 380ppm minimum).
VCXO tuning range: 0V - V
DD
V.
Uses inexpensive fundamental-mode parallel
resonant crystals (from 20 to 52MHz).
2.5V or 3.3V supply voltage.
Selectable High Drive (30mA) or Standard Drive
(10mA) CMOS output.
Available in 8-Pin SOIC or TSSOP.
DESCRIPTION
The PLL502-51 is a monolithic low jitter, high per-
formance CMOS VCXO IC. It allows control of the
output frequency with an input voltage (VCON), us-
ing a low cost crystal.
This makes the PLL502-51 ideal for a wide range of
applications from 20MHz to 52MHz (including
27MHz, 35.328MHz, etc.).

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 con-
ditions above the operational limits noted in this specification is not implied.
* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.

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 nomi-
nal 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
