D19m Technical Description
Date printed:
30.06.20
D19m E33
SYNC INT
= the internal sync generator is used (in case no external sync
signal is available).
SYNC EXT
= TTL sync or AES sync input is used.
48/44.1/32
The current sampling frequency of the digital output will be indicated.
Jumpers:
AES / TTL
AES:
The sync input from the AES/EBU input is used (in case of standalone
use of the SFC card).
TTL:
The sync input from the D19m rack is used. The internal TTL sync
signal is generated by the MADO card in a D19m MUX frame.
Bit Setting
16, 18, 20, 24 bit.
REM / TDM
TDM
(default): no U-bit handling.
REM
(remote): will be used for additional external U-bit handling (not im-
plemented yet).
EXT / INT
INT
(internal): the internal reference is used, independent of the sync input.
EXT
(external): the card is synced to the AES sync input (jumper AES-TTL
set to AES) or to the TTL sync (jumper AES-TTL set to TTL).
