The GPS7900 is a High Precision Broadcast-Grade frequency-standard GPS satellite synchronizer based on 1PPM ultra-high stability oscillators ( rubidium available as option ), ideally suited to provide the 10MHz and 1PPS sync and timing information to any application where absolute precision is required.
Typical applications includes DVB-T / DVB-H SFN transmitters and MIP inserters synchronization, NTP operations, etc. The GPS7900 comes complete with EXTERNAL GPS ANTENNA to be connected to the module via standard low-loss 50 OHM coax cable with N male connector ( to the antenna ) and BNC connector ( to the module ) , RS232 + WEB + SNMP control.
In case of satellite signal loss, ( no signal or no antenna ) the GPS7900 continues providing the timing information, the 10Mhz + 1PPS with total HIGH accuracy form many days without any drift problem. |
