Manufacturer:WAVECOM Description: The 10-bit ROW_ADDR (row address) input bus selects the pixel row to be read for each readout cycle. The ROW_STRT_N signal starts the process of reading the analog data from the pixel row, the analog-to-digi- tal conversion, and the storage of the digital values in the ADC registers. When these actions are completed, the sensor sends a response back to the system con- troller using the ROW_DONE_N. Row address must be valid for the first half of the row processing time (the period between ROW_START_N and ROW_DONE_N). The MI-MV13 contains a pipeline style memory array, which is used to store the data after digitization. This memory also allows the data from the previous row conversion cycle to be read while a new conver- sion is taking place. The digital readout is controlled by lowering the LD_SHFT_Nsignal,followedbythe DATA_READ_EN_N signal. LD_SHFT_N transfers the digitized data from the ADC register to the output reg- ister. DATA_READ_EN_N is used to enable the data output from the output register. A new pixel row read- out and conversion cycle can be started two clock cycles after DATA_READ_EN_N is pulled low. The out- put register allows the reading of the digital data from the previous row to be performed at the same time as a new conversion (pipeline mode). This means that the total row time will be only that between when: (a) the ROW_STRT_N signal is applied and ROW_DONE_N is returned; and (b) LD_SHFT_N and DATA_READ_EN_N are applied plus two clock cycles. The pipelined opera- tion means there will always be 1 row of latency at the start of sensor operation. The alternative to pipelined operation is burst data operation in which a new pixel row conversion is not initiated until after the output register is emptied (and LD_SHFT_N has been taken high). The ratio of line active and blanking times can be adjusted to easily match a variety of display and collection formats. See Timing Diagram For One Row on page 7. |
