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 75 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:

Internal voltage reference. 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 load.(75 external and 33 internal) Backlight mode 2
