R/W Reset Description
15:11 RW 0_h Reserved. Do not change.
Data Rate Detection Enable.
Selects which data rates will be
reported on the INT pin when
INT_SOURCE_SELECT is set to 100_b
or 101_b. Set the corresponding bit
10:6
RW
0_h
to 1 to enable detection reporting
for each rate.
Bit 0 = < MADI
Bit 1 = MADI
Bit 2 = SD
Bit 3 = HD
Bit 4 = 3G
Selects the internal signal source
for the INT pin.
000_b = Loss of Signal (LOS), filtered
per registers
LOS_FILTER_CONF_REG_0 and
LOS_FILTER_CONF_REG_1
001_b = Specific signal presence
status as selected by
INT_CD_MODE_SELECT
5:3
RW
0_h
010_b = Reserved
011_b = An active-high minimum
200ns pulse generated upon each
detected change in the rate.
100_b = CD qualified with rate(s)
selected by
DATA_RATE_DETECTION bits
101 = Same as settings above, with
a minimum 200ns low pulse when
a rate change is detected
110_b/111_b = Reserved
Carrier Detect Mode, allows INT to
assert only for selected rate.
000_b = General Carrier Detect (CD)
(any rate)
001_b = CD for below-MADI rates
2:0
RW
0_{h 010b = CD for MADI rates}
011_b = CD for SD
100_b = CD for HD
101_b = CD for 3G
110_b, 111_b = Reserved
15:0 RO 0_h Readout of chip “version_id”.
