Data Sheet
Description
Synchronization source selection
One S/T interface can be selected as
synchronization source (in TE mode only)
’000’ = source is S/T interface 0
’001’ = source is S/T interface 1
’010’ = source is S/T interface 2
’011’ = source is S/T interface 3
’100’ = source is S/T interface 4
’101’ = source is S/T interface 5
’110’ = source is S/T interface 6
’111’ = source is S/T interface 7
Automatically synchronization source selection
’0’ = automatically selection of synchronization
source. A TE which is synchronized to the
incoming S/T signal (e.g. state F6 or F7) is chosen
as sync source and V_SYNC_SEL is ignored.
’1’ = V_SYNC_SEL is used for synchronization
source
Must be ’0000’.
