OV5116N

OV5116N OV5116N SINGLE IC CMOS MONOCHROME CAMERA WITH NTSC ANALOG OUTPUT Features Single chip 1/4 inch format video image sensor EIA/NTSC output Selectable mirror image Auto gain control (maximum + 18 dB) High I.R. sensitivity for nighttime applications Auto and manual backlight compensation mode Gamma correction -On/Off External frame sync capability 40mw on-chip power consumption External data acquisition support Smear free Auto level expanding Optional edge enhancement General Description The OV5116N is a complete black and white CMOS Video Camera chip. It conforms to EIA/NTSC (60 Hz) standards and outputs composite video capable of directly driving a 75Ω display device. The on-chip auto exposure allows for a wide range of lighting conditions, eliminating the need for external mechanical shutter components. This, along with its single supply, low power consumption makes the OV5116N an incredibly versatile and cost-effective video camera perfect for the following types of applications: Applications Security Surveillance Machine Vision Process Control CCTV Infant Monitoring Toys VRCHG VREQ AVDD DEVDD Key Specifications Array Size Effective Image Area 25 DEGND 24 ATBLKT Auto Electronic Exposure (seconds) Minimum Illumination S/N Ratio Power Supply Power Requirements Package Type 320 x 240 pixels 3.2 x 2.5mm N50 SVDD 4 ABOFF VCBRT 5 6 3 2 1 AGND 28 27 26 1/60-1/6000 0.5 lux @ f 1.4 (3000k) 46 dB (AGC=1x) 5VDC, ±5% (40 mw beforeloading), 70mw standard loading 28 pin LCC SGND 7 NTSC 8 BKLT 9 XTAL2 10 XTAL1 11 12 FSI OV5116N 28 PIN LCC 23 OVDD 22 CVO 21 DGND 20 DVDD 19 PCLK/G8X 13 14 15 16 OENB BPED G4X FAST 17 18 FSO/MIRR GAMMA OV5116N PIN ASSIGNMENT OmniVision Technologies, Inc. 930 Thompson Place Sunnyvale, CA 94085 U.S.A.

Connect to AGND with a 0.1uF capacitor. Set low(Ø)=standard NTSC. Set high (1)=50hz light (For use in Japan Only); Auto brightness level descending function off Video DC Output Black level, leave it open in usual case Ground connections. Connect to supply common. Set high(1)=EIA/NTSC mode Backlight mode 1 Oscillator clock output or crystal output. External oscillator input or crystal input: 12.288MHz External frame sync input. A rising edge on FSI sets the chip timing to vertical sync. Leave open if unused. A logic level input to enable or tri-state CVO. Logic high(1)=tri-state;low(Ø)=enabled. A logic level input which when high places the maximum AGC gain to 4x. When low the sensor AGC gain is 2x. A logic level input to enable/disable AGC/AEC FAST mode. High enables, low disables, which provides slow and smooth AGC/AEC mode. A logic level input to disable on chip edge enhancement. High disable, low enable. A logic level pin to select the transfer characteristic of output voltage versus light input. Logic high for g=0.45; low for g=1. In/out pin.Frame Sync Output. Digital frame sync output pin. Positive pulse occurs during the CVO vertical sync period. Input is a logic level input to enable mirror function. Low(Ø)=Standard, High(1)=Mirror. Digital pixel clock output. Provides 2 functions: When high a valid pixel is present at CVO and in sync with PCLK. Input is a logic level input to enable maximum AGC gain to 8x (only effective when pin 14 is set to high(1)) The composite video output signal. The output is a source follower capable of directly driving a 1V p-p signal into a 108 Ω load.(75Ω external and 33Ω internal) Backlight mode 2 19 PCLK/G8X I/O Ø/Ø 22 *24 CVO ATBLKT Q I-Ø 27 VREQ OA Internal voltage reference level.
