100 MHz Connectorized Phase-Locked Crystal Oscillator with Reference-Detect Switch

EMResearchThe PLXO-100 from EM Research is a phase-locked crystal oscillator operating at 100 MHz in a miniature connectorized package (1.5” x 1.5” x 0.6”). Locked to an external 10 MHz frequency reference, the device exhibits exceptionally-low phase noise (-130 dBc/Hz @ 1 KHz offset), low spurs (-70 dBc), +0 dBm output power on a supply voltage of +12 VDC. The addition of an internal reference-detect switch enables the user to employ the external frequency reference that, if disabled, will automatically switch to an internal 10 MHz reference, thereby providing uninterrupted use of the PLXO-100.

EM Research offers the PLXO Series in a surface-mount (0.9” x 0.9” x 0.15”) or connectorized package at custom fixed-frequencies from 5 to >500 MHz. The PLXO Series features low jitter (<0.05 pSec. RMS @ 100 MHz, typical), optional internal references and select supply voltages (+3.3, +5, +8, +12 or +15 VDC). PLXO devices are ideal for use with A-D/D-A converters, carrier recovery loops, system clocks, or as reference sources for Ku and K-Band frequency converters.
