Raj, JLT just sent out a press release some days ago on the LC_XO sub 1 inch square GPSDO that is smaller and higher performance than the RFX unit, runs from only 3.3V, and it can be soldered into a 100 mil standard breadboard, and consumes only about 0.5W (RFX unit is probably 1W).

Don, Check out the JLT GPSTCXO eval board, plug and play no pcb layout required, very good performance if shielded from airflow, delivery from stock less than 1week, much lower power, gpstcxo itself w/o eval board is similar size. Supports WAAS, Egnos and Msas too. Supported by Ulrichs
