Outfitted with differential LVPECL output, the CVPD-922 voltage-controlled crystal oscillator from
Crystek offers one of the industry’s lowest noise floors at -162 dBc/Hz. Close-in phase noise has
been reduced to -85 dBc/Hz at a 10-Hz offset. The manufacturer
reports that this overall ultralow phase noise results in typical
phase jitter of 85 femtoseconds (12 kHz to 20 MHz), making the
part suitable for such applications as high-definition video
broadcast equipment.
The oscillator covers a frequency range of 40 MHz to 125 MHz
and provides a minimum pulling range of ±20 ppm APR (absolute
pulling range). It accepts an input voltage of 3.3 V ±0.3 V with a
control voltage of 1.65 V ±1.65 V. Supplied in a 9×14-mm
surface-mount package, the CVPD-922 operates over a
temperature range of 0°C to 70°C (optionally from -40°C to +85°C).
