electronica 2014: IQD unveils GPS disciplined OCXO

Unveiled at electronica this week, the new design incorporates an internal GPS receiver with a 1PPS output and is housed in a 14pin 60mm square package. When coupled to an external aerial via the incorporated SMA connector, in the event of the loss of the GPS signal, the 10MHz OCXO will switch-in with a holdover capability of 1.5 µSeconds for a 24 hour period, thereby maintaining lock until restoration of the reference signal. The standard operating temperature range of the module is -20 to 75 °C, although other temperature ranges and holdover specifications can be considered on request. The required power supply is 5V with the output being standard HCMOS. Current consumption is 2A maximum during warm up with this reducing to 1A once the steady-state condition is reached. Full details are available from IQD on Stand 314 in Hall B5.
