LYNX Manual RA02
IPX-4M15-L
In single mode, each line consists of 12 empty pixels (E1 – E12),
followed by 28 masked pixels used for black (dark) reference (R1 –
R28), followed by 4 buffer pixels (B1 – B4), followed by 2048 active
data pixels (D1 – D2048), followed by 4 buffer pixels (B1 – B4), and
followed by another 28 masked dark pixels (R1 – R28) – Figure 2.20.
In the dual mode, each line consists of 12 empty pixels (E1 – E12),
followed by 28 masked pixels used for black (dark) reference (R1 –
R28), followed by 4 buffer pixels (B1 – B4), followed by 1024 active
data pixels – Figure 2.21. The data is sampled on the rising edge of the
clock, and the LVAL (line valid) signal is active only during the active
pixels. Each frame consists of 122.1 us vertical frame timing for single
mode (95.7 us for dual mode), followed by 10 masked dark lines (RL1
– RL10), followed by 6 buffer lines (BL1 – BL6), followed by 2048
active lines (DL1 – DL2048), and followed by 8 buffer lines (BL1 –
BL8). During each frame the FVAL (frame valid) signal is active only
during the active lines (DL1 – DL2048) – Figure 2.22.
