RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

EM Research Press Release - October 13, 2011
EM Research Intros 100 MHz Connectorized Phase-Locked Crystal
-- Featuring Low Phase Noise, Fine-Tuning Steps
Oscillator with Reference-Detect Switch
The 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.
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
