    User Manual for AZ420 Telco Satellite Modem Features 6 FEATURES Clocking Parameters and Schemes 6.1.1 Clock Selection Possibilities Figure 11 - Clock Selection Possibilities There are three Master Clock Selection possibilities: • Internal clock; • External G703; • 10Mhz input (optional).

  • Page 47: Deframer Buffer (Doppler Buffer)

    User Manual for AZ420 Telco Satellite Modem Features Output Clock Selection : • Internal; • External G703; • Clock from satellite. The output clock selection determines the clock source that is used to clock the data on the G703 TX interface. The system runs on its own internal clock by selecting “internal”.

  • Page 48: Typical Application

    User Manual for AZ420 Telco Satellite Modem Features In case of clock slaving via satellite the buffer must be twice this value because the transmit clock has also Doppler shift. The internal clock is normally only used when the master clock is set to a very accurate (external) reference and is very close to the TX clock.
