The PYTHON 480 is also configurable in a CMOS output configuration, which includes a 10−bit parallel CMOS output together with a CMOS clock output and ‘frame valid’ and ‘line valid’ CMOS output signals. LVDS Interface Mode LVDS Output Channels The image data output occurs through one LVDS data channel where a synchronization LVDS channel and an LVDS output clock signal synchronizes the data. The one data channel is used to output the image data only. The sync channel transmits information about the data sent over the data channel (includes codes indicating black pixels, normal pixels, and CRC codes). Frame Format The frame format is explained by example of the readout of two (overlapping) windows as shown in Figure 30(a). The readout of a frame occurs on a line−by−line basis. The read pointer goes from left to right, bottom to top. Figure 30 indicates that, after the FOT is completed, the sensor reads out a number of black lines for black calibration purposes. After these black lines, the windows are processed. First a number of lines which only includes information of ‘ROI 0’ are sent out, starting at position y0_start. When the line at position y1_start is reached, a number of lines containing data of ‘ROI 0’ and ‘ROI 1’ are sent out, until the line position of y0_end is reached. From there on, only data of ‘ROI 1’ appears on the data output channels until line position y1_end is reached During read out of the image data over the data channels, the sync channel sends out frame synchronization codes which give information related to the image data that is sent over the four data output channels. Each line of a window starts with a Line Start (LS) indication and ends with a Line End (LE) indication. The line start of the first line is replaced by a Frame Start (FS); the line end of the last line is replaced with a Frame End indication (FE). Each such frame synchronization code is followed by a window ID (range 0 to 7). For overlapping windows, the line synchronization codes of the overlapping windows with lower IDs are not sent out (as shown in the illustration: no LE/FE is transmitted for the overlapping part of window 0). NOTE: In Figure 30, only Frame Start and Frame End Sync words are indicated in (b). CRC codes are also omitted from the figure. For additional information on the synchronization codes, refer to Application Note AND5001. |
