ROX2525T5 Datasheet, PDF (1/2 Pages) TEMEX – The ROX2525T5 OCXO presents interesting stability performance versus price

DISCRETE OCXO | STANDARD OCXO
ROX2525T5 (Not Recommended for New Designs)
The ROX2525T5 OCXO presents interesting stability performance versus price. Frequencies available are from 10MHz to 65MHz, and power
supply options are 3.3V, 5V & 12V. These 25 x 25 mm package series of oscillators are designed with direct heating on a single board. For
new designs, ROX2522S4 is recommended.
