DESCRIPTION
VCON GND GND
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.

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.
