However you will need to replace the 10.95MHz crystal with a 10.95Mhz source phase locked to the OCXO being disciplined. The 3.3V version of this module has been available at very low cost from time to time on ebay. Whilst not suitable for production purposes they should be more than adequate for experimental purposes.
