... Sensor (APS) Analog Processing Functional Overview The MT9V012 is a progressive-scan sensor that generates a stream of pixel data qualified by LINE_VALID and FRAME_VALID signals. It uses an input master clock of 27 MHz (nominal). The data rate (pixel clock) is one half of the master clock frequency, which means that one pixel is generated every two master clock cycles. Figure 1 shows the sen- sor block diagram ...
Page 7
... Operating Modes The functional operating mode of the MT9V012 is controlled by the MODE1 and MODE0 inputs (Table 2). These inputs should be driven to a static logic 1 or static logic 0 level during normal operation. Table 2: Functional Mode Selection Mode1 Default Mode This section shows a typical configuration schematic for the MT9V012 operating in default mode ...
Page 8
... Serial Mode This section shows a typical configuration schematic, including the ball diagram and ball description, for the MT9V012 operating in serial mode. This mode operates only at 2.5V to 3.1V V Figure 3: Typical Configuration: Serial Mode MASTER CLOCK (162 MHz) From Controller Notes: 1. All power supplies should be adequately decoupled. ...

... Pixel Array Structure The MT9V012 pixel array is configured as 695 columns by 504 rows (shown in Figure 4). The first 34 columns and the first 14 rows of pixels are optically black, and are used for the automatic black level adjustment (“Black Level Calibration” on page 40). The last 12 columns and the last row of pixels are also optically black ...
Page 10
... When the image is read out of the sensor read one row at a time, with the rows and columns sequenced as shown in Figure 5. By convention, data from the sensor is shown with the first pixel read out—pixel (34,14) in the case of the MT9V012—in the top left- hand corner (Figure 7). ...

... LINE_VALID, FRAME_VALID, and D a clock to sample the data. PIXCLK is continuously enabled, even during the blanking period. The MT9V012 can be programmed to delay the PIXCLK edge relative to the D transitions from 0 to 3.5 master clocks, in steps of one-half of a master clock. This can be achieved by programming the corresponding bits in Reg0x0A. The parameters P, A, and Q in Figure 9 are defined in Table 3 on page 12 ...

... Output Data Format (Serial Mode) The MT9V012 image data is read out in a progressive scan. In serial mode, valid image data is surrounded by horizontal blanking and vertical blanking, as shown in Figure 7 on page 10. However, unlike default mode, serial mode provides pixel data and timing strobes combined into a single serial bit stream. Electrically, this bit stream uses LVDS on the D In serial mode, each pixel is encoded as a 12-bit value by adding a start bit and a stop bit ...

... The master then transfers the data, 8 bits at a time, with the slave sending an acknowledge bit after each 8 bits. The MT9V012 uses 16-bit data for its internal registers, thus requiring two 8-bit transfers to write to one register. After 16 bits are transferred, the register address is automatically incremented, so that the next 16 bits are written to the next register address ...

... The paging mechanism is intended to allow access to other sets of registers when the sensor is embedded as part of a more complex integrated sub-system (for example SOC). All of the registers within the MT9V012 are accessible on page 0 (the default page). PDF: 814eb99f/Source: 8175e929 MT9V012_2.fm - Rev. B 2/05 EN ...

... Some sensor settings cannot be changed during frame readout. For example, changing Reg0x03 (row width) partway through frame readout would result in inconsistent LINE_VALID behavior. To avoid this, the MT9V012 double buffers many registers by implementing a “pending” and a “live” version. Reads and writes access the pending register ...

... When the sensor is configured in serial mode, the LVDS output remains driven when the sensor is in the standby state. Floating Inputs Many MT9V012 signals use bidirectional pads. There are three reasons for this: • The signal associated with the pad is bidirectional in normal use (the only signal in this category is S • ...
Page 43
... This leads to two areas where the design application should be reviewed: 1. When using the output enable control (“Output Enable Control” on page 41), ensure that all MT9V012 bidirectional pads that enter a high- impedance state are driven to a valid logic level. 2. When operating the MT9V012 in serial mode ensure that unused bidirectional pads are terminated correctly ...
Page 44
... Reg0x65 can be used to bypass the clock gating, so that clocks to individual domains run continuously. When the MT9V012 enters a low-power state, almost all of the internal clocks are stopped. The only exception is that a small amount of logic (approximately 10 flip-flops) is clocked so that accesses to the two-wire serial interface continue to function correctly. ...
