SNLS708 February 2023 DS90UB638-Q1
PRODUCTION DATA
The DS90UB638-Q1 counts the number of received lines (long packets) to determine line count on LINE_COUNT_1 and LINE_COUNT_0 registers 0x73–74. For received line length, DS90UB638-Q1 reads the number of bytes per line in LINE_LEN_1 and LINE_LEN_0 registers 0x75–0x76. Line Count and Line Length values are valid when receiving a single video stream. If multiple virtual channels are received on a FPD-Link III Receive port in CSI-2 input mode, the values in registers 0x73-74 may not be accurate
