Telum GPSTC-AMC is a GPS clock AdvancedMC that provides a highly stable 30.72 MHz clock output that is phase aligned to the Global Positioning System (GPS) derived 1 PPS input. This GPS clock AdvancedMC provides extremely precise, highly reliable GPS clock synchronization for applications such as WiMAX base stations.

GPSTC-AMC implements a temperature-compensated voltage-controlled crystal oscillator with a 30.72 MHz center frequency and a minimum Stratum 3 stability of 0.37 PPM. The oscillator output is phase aligned to a 1 PPS clock input that is derived from the GPS satellite network. This very low jitter onboard crystal oscillator enables the microprocessor to filter out the short term jitter that often affects GPS derived 1 PPS clocks while taking advantage of its long term precision.
