The PLXO-250 Phase-Locked Crystal Oscillator from EM Research operates at 250 MHz in a miniature connectorized package (1.5” sq x 0.6”). Featuring low spurs (-70 dBc), extremely-low harmonics (-50 dBc) and sub-harmonics (-70 dBc), the unit is locked to a 10 MHz external reference (or optional internal reference), and exhibits exceptionally-low phase noise (-120 dBc/Hz @ 1 kHz), +7 dBm output power (MAX), while operating on a supply voltage of +12 VDC.

The PLXO-250 is ideal for use with A/D & D/A converters, GPS carrier recovery loops or as reference sources for Ka-Band and mm-Wave frequency converters, and various test equipment.
