Bliley Technologies’ NV47AG is an ovenized crystal oscillator (OCXO) available in frequencies from 5 MHz to 13 MHz, featuring high single stability and an ultra-low-profile package (less than 0.5 in.). For example, for a 10 MHz unit, aging is ±50 ppb for one year. The OCXOs also offer very low phase noise options for both square wave and sine wave output signals. The maximum frequency variation range is ±5.0 ppb. Other specifications include 5 V or 12 V supply options, and CMOS and sine-wave output options.
