DESCRIPTION
The PLL502-39U (LVDS) is a high performance and
low phase noise VCXO clock IC. It provides phase
noise performance as low as –125dBc at 10kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x. The wide pull range (+/- 200 ppm)
and very low jitter makes this ideal for a wide range
of applications, including SONET/SDH and FEC.
PLL502-39 accepts fundamental parallel resonant
mode crystals input from 12 to 25MHz.
Note: ^ designates Internal pull-up

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: 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.
