14.15 Reference Clock
MDM9000 >> Ref Clock
Configure the reference clock.
This reference signal for an outdoor BUC is multiplexed on the L-band Tx or on the 10 MHz REF out
interface of the back panel.
(Note, this 10 MHz REF out is an optional interface.)
A reference clock can be generated internally (default) or slave on an external source.
The internal reference clock is 10 MHz.
The clock reference has the following specifications:
10 MHz Ref
Specifications
Internal clock reference Stability ± 2000 ppb over 0 to 70°C
Ageing ± 1000 ppb/year
Very High Stability (optional) Stability ±2x10e-9 over 0°C to 65°C
Ageing: ± 0.5 ppb/day
± 500 ppb/10 year
When an external source is selected (attached to 10 MHz ref In interface), the following frequencies
can be inserted.
1 MHz, 2 MHz, 5 MHz, 10 MHz or 20 MHz.
Select the external clock reference for synchronization with other devices to have a higher stability
than the internal default stability.
