10kHz offset).
Integrated variable capacitors.
Wide pull range (+/- 250 ppm).
Low jitter (RMS): 10ps period.
Integrated audio Phase Locked Loop.
Audio clock output (ideal for 8.192MHz,
11.2896MHz, 12.288MHz).
27MHz crystal input.
Audio Reference clock input.
3.3V operation.
Available in 16-Pin SOIC.
DESCRIPTION
The PLL502-26 is a low cost, high pull-range and
low phase noise VCXO, providing less than -135dBc
at 10kHz offset at 27MHz. It also integrates an Audio
clock phase locked loop ideal for the 8.192MHz,
11.2896MHz and 12.288MHz audio outputs, starting
from an audio reference clock. Its very high pull
range makes it ideal for Digital Video applications,
allowing users to save board space and cost.

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.
* 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
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.
