[time-nuts] Trimble TB PCB board gpsdo question
Hi, anybody has the Trimble Thunderbolt GPSDO but in a letter size PCB board from the Hong-Kong epay seller It has a SMC socket and beside the normal 10 MHz output it has a second frequency output 9,830400 MHz. What is the purpose for this freq in the GSM base station... Please contact me offline to exchange some experience, data. Many thanks and best regards Ernie. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

But it is 8 times the CDMA chip rate of 1.2288 MHz, so would be useful in a CDMA base station. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
