PRODUCTION DATA.
The lane and frame alignment monitoring and character replacement are as per the JESD204B standard. The insertion of frame and lane alignment characters can be enabled by setting the LANE_ALIGN and FRAME_ALIGN register controls. These controls, in conjunction with the SCR_EN control, determine the mechanism of the lane and frame alignment character replacement, as shown in Table 25.
SCR_EN | FRAME_ALIGN | LANE_ALIGN | EFFECT ON LINK DATA |
---|---|---|---|
0 | 0 | 0 | ADC data are sent without any character replacement. |
0 | 0 | 1 | If the last octet of the multiframe is the same as the last octet of the previous multiframe, then the last octet is replaced with /K28.3/. |
0 | 1 | 0 | If the last octet of the frame is the same as the last octet of the previous frame, then the last octet is replaced with /K28.7/. If an alignment character has already been sent in the previous frame, then no characters are replaced. |
0 | 1 | 1 | Frame and lane alignment character replacements are enabled. |
1 | 0 | 0 | ADC data are scrambled and sent without any character replacement. |
1 | 0 | 1 | If the last scrambled octet of the multiframe is D28.3, then that octet is replaced with /K28.3/. |
1 | 1 | 0 | If the last scrambled octet of the frame is D28.7, then that octet is replaced with /K28.7/. |
1 | 1 | 1 | Frame and lane alignment character replacements are enabled with scrambling. |
