SINGLE IC CMOS MONOCHROME CAMERA WITH PAL ANALOG OUTPUT OV5116P 1. Introduction This section describes the features and functions of the OV5116P, a monochrome CMOS video camera integrated circuit. 2. Pin Assignments: Table 1. Pin Descriptions Pin # Name 1, 2, 20, 23, 26 AVDD, SVDD, DVDD, OVDD DEVDD Class Bias Function Power (+5V) connections. 3 VRCHG OA Internal voltage reference. Connect to AGND with a 0.1uF capacitor. 4 N50 I-Ø Set high(1)=PAL 5 ABOFF I-Ø Auto brightness level descending function off 6 VCBRT OA Video DC Output Black level, leave it open in usual case 7, 21, 25, 28 SGND, DGND, DEGND, AGND Bias Ground connections. Connect to supply common. 8 PAL I-1 Set low(Ø)=CCIR/PAL mode. *9 BKLT I-Ø Backlight mode 1 10 XTAL2 XO Oscillator clock output or crystal output. 11 XTAL1 XI External oscillator input or crystal input; 13.5MHz 12 FSI I-Ø External frame sync input. A rising edge on FSI sets the chip timing to vertical sync. Leave open if unused. 13 OENB I-Ø A logic level input to enable or tri-state CVO. Logic high(1)=tri-state;low(Ø)=enabled. 14 G4X I-Ø A logic level input which when high places the maximum AGC gain to 4x. When low the sensor AGC gain is 2x. 15 FAST I-Ø A logic level input to enable/disable AGC/AEC FAST mode. High enables, low disables, which provides slow and smooth AGC/AEC mode. 16 BPED I-Ø A logic level input to disable on chip edge enhancement. High disable, low enable. 17 GAMMA I-1 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. 18 FSO/MIRR I/O 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. Ø/Ø 19 PCLK/G8X I/O Ø/Ø 22 CVO Q *24 ATBLKT I-Ø 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 27 VREQ OA Internal voltage reference level.
