Table 51. Lane1_0_Ctrl (address 0871h)
Default values are highlighted.
Bit Symbol Access Value Description
7 - - 0 not used
6 SCR_IN_MODE R/W defines the input type for scrambler and 8-bit/10-bit units:
0 (reset) (normal mode) = input of the scrambler and 8-bit/10-bit
units is the output of the frame assembly unit.
1 input of the scrambler and 8-bit/10-bit units is the PRBS
generator (PRBS type is defined with “PRBS_TYPE”
(Ser_PRBS_Ctrl register)
5 to 4 LANE_MODE[1:0] R/W defines output type of lane output unit:
00 (reset) normal mode: lane output is the 8-bit/10-bit output unit
01 constant mode: lane output is set to a constant (0x0)
10 toggle mode: lane output is toggling between 0x0 and 0x1
11 PRBS mode: lane output is the PRSB generator (PRBS type is
defined with “PRBS_TYPE” (Ser_PRBS_Ctrl register)
3 - - 0 not used
2 LANE_POL R/W defines lane polarity:
0 lane polarity is normal
1 lane polarity is inverted
1 LANE_CLK_POS_EDGE R/W defines lane clock polarity:
0 lane clock provided to the serializer is active on positive
edge
1 lane clock provided to the serializer is active on negative edge
0 LANE_PD R/W lane power-down control:
0 lane is operational
1 lane is in Power-down mode
Table 52. ADCA_0_Ctrl (address 0890h)
Default values are highlighted.
Bit Symbol Access Value Description
7 to 6 - 00 not used
5 to 4 ADC_MODE[1:0] R/W defines input type of JESD204A unit:
00 (reset) ADC output is connected to the JESD204A input
01 not used
10 JESD204A input is fed with a dummy constant, set to: OTR = 0
and ADC[11:0] = “100110111010”
11 JESD204A is fed with a PRBS generator (PRBS type is defined
with “PRBS_TYPE” (Ser_PRBS_Ctrl register)
