OXCO claims to be quietest and most accurate yet
01 April 2014
According to Connor Winfield, the OX200-SC, SC cut crystal oscillator is its most quiet, accurate and stable 10MHz OCXO to date.
It is designed for use in IP backhaul using IEEE1588 PTP master clock that requires very high fre¬quency stability, very tight initial calibration and very low aging. These specifica-tions may eliminate or greatly extend the time for initial or periodic re-calibration.
The 12V DC, ovenised third overtone SC cut crystal oscillator with electronic frequency control is offered in a CO-8 package. Its frequency stability is ±1.5ppb within the temperature range of 0 to 70°C. Frequency calibration is guaranteed to be less than ±25 ppb with EFC set to 2.5V. Frequency control can vary the frequency ±0.2 ppm over 0 to4V.
Aging is specified to be less than 0.2ppb/day after 30 days and 60ppb total after five years. Frequency toler¬ance for five years is guaranteed to be less than 0.1ppm. Stability over 5% voltage or load variations is less than ±0.3ppb.
The output is a 10MHz LVCMOS output. Typical phase noise levels are -85dBc/Hz at 1Hz, -115dBc/Hz at 10 Hz, -135dBc/Hz at 100Hz, -145dBc/Hz at 1kHz, and -150dBc/Hz at 10kHz.
It is housed in a standard 5pin hermetically sealed Euro CO8 package with a 13.46mm height, 36x 27mm. It is RoHS-compliant and lead free.
