Device Configuration using M1 & M2
The configuration signals M1 and M2 are both
1 sampled on the 2nd rising edge of the CLK input signal after a L->H
or H->L transition on /SYNC. Depending on the polarity of this last transition on /SYNC, M1 and M2 are interpreted
differently by THS8135, as shown in Table 4.
Table 4: Interpretation of M1
If
last
event on
/SYNC
is:
Then M1 is interpreted
on 2
nd CLK rising edge
following this event as:
Description
H->L
BLNK_INT
Sets operation with Full or Video (ITU-R.BT601)- compliant code Input Range.
Selection available in both generic and video modes i.e. the full-scale range is
reached from either the 0-1023 code range or the code range of Table 8.
L->H
M1_INT
Sets device operation mode. See Tables 6 & 7.
Table 5: Interpretation of M2
If
last
event on
/SYNC
is:
Then M2 is interpreted
on 2
nd CLK rising edge
following this event as:
Description
H->L
INS3_INT
Sets Sync Insertion mode: /SYNC low enables sync generation on 1
(INS3_INT=L) or all 3 (INS3_INT=H) DAC outputs. SYNC_T determines the
sync polarity.
L->H
M2_INT
Sets device operation mode. See Tables 7 & 8.
Selection of Color Space and Input Formatter Mode
1 In THS8133, only M2 is a sampled signal while M1 is continuously interpreted. By doing so here, the additional
input control signal BLNK_INT is generated. See paragraph on backward compatibility with THS8133.
