Frequency/Time Standard Uses GPS and OCXO Technology

Mon, 09/15/2008 - 9:14am

Suntsu SGPS2Having PCB mountability with a MMCX antenna connection on the side, Suntsu Frequency Control’s SGPS2 Series frequency and time standards combine a 16-channel GPS receiver with Suntsu’s OCXO technology in a 2” × 2” × 1.25” package. The OCXO frequency is disciplined with timing signals from the GPS satellites to maintain frequency accuracy to less than 1x10-12 in 24 hours. An Adaptive Algorithm changes the control loop coefficients as the environmental conditions change to maintain exact accuracy of the 1PPS to less than 20 ns and holdover to less than 1 µs in two hours. An alternative 1PPS input selected through the serial interface can be used in place of the GPS antenna input.  The units are well suited for applications like CDMA and E911.
