ROX3627T3 Datasheet, PDF (1/2 Pages) TEMEX – The ROX3627T3 OCXO is a cost effective stable oscillator for telecom applications

DISCRETE OCXO | STANDARD OCXO
ROX3627T3 (Not Recommended for New Designs)
The ROX3627T3 OCXO is a cost effective stable oscillator for telecom applications. Its total stability is less than 50 ppb per year across all
causes, less than 20 ppb with the higher package. Frequencies available are from 5 MHz to 40 MHz, and power supply options are 3.3 V, 5 V
& 12 V. These 36 x 27 mm package series of oscillators are designed with direct heating on a single board. They are optimized designs for the
Stratum 3E and up to Stratum 2. For new designs, ROX3827T3 is recommended.
Features
