4 / 32 page MT9P031 www.onsemi.com 4 Table 3. PIN DESCRIPTION Name Type Description RESET_BAR Input When LOW, the MT9P031 asynchronously resets. When driven HIGH, it resumes normal operation with all configuration registers set to factory defaults. EXTCLK Input External input clock. SCLK Input Serial clock. Pull to VDD_IO with a 1.5 kΩ resistor. OE Input When HIGH, the PIXCLK, DOUT, FV, LV, and STROBE outputs enter a High-Z. When driven LOW, normal operation resumes. STANDBY_BAR Input Standby. When LOW, the chip enters a low-power standby mode. It resumes normal operation when the pin is driven HIGH. TRIGGER Input Snapshot trigger. Used to trigger one frame of output in snapshot modes, and to indicate the end of exposure in bulb exposure modes. SADDR Input Serial address. When HIGH, the MT9P031 responds to device ID (BA)H. When LOW, it responds to serial device ID (90)H. SDATA I/O Serial data. Pull to VDD_IO with a 1.5 kΩ resistor. PIXCLK Output Pixel clock. The DOUT, FV, LV, and STROBE outputs should be captured on the falling edge of this signal. DOUT[11:0] Output Pixel data. Pixel data is 12-bit. MSB (DOUT11) through LSB (DOUT0) of each pixel, to be captured on the falling edge of PIXCLK. FRAME_VALID Output Frame valid. Driven HIGH during active pixels and horizontal blanking of each frame and LOW during vertical blanking. LINE_VALID Output Line valid. Driven HIGH with active pixels of each line and LOW during blanking periods. STROBE Output Snapshot strobe. Driven HIGH when all pixels are exposing in snapshot modes. VDD Supply Digital supply voltage. Nominally 1.8 V. VDD_IO Supply IO supply voltage. Nominally 1.8 or 2.8 V. DGND Supply Digital ground. VAA Supply Analog supply voltage. Nominally 2.8 V. VAA_PIX Supply Pixel supply voltage. Nominally 2.8 V, connected externally to VAA. AGND Supply Analog ground. VDD_PLL Supply PLL supply voltage. Nominally 2.8 V, connected externally to VAA. TEST − Tie to AGND for normal device operation (factory use only). RSVD − Tie to DGND for normal device operation (factory use only). NC − No connect. |
