Ai3152
Digital Signal Processor for Color CCD Camera
General Description
The Ai3152 is the digital signal-processing chip for color video camera. It includes timing generator
and digital/analog output. Supports 250K / 380K NTSC system CCD sensors and 290K / 440K PAL
system CCD sensors with complementary color filter. It also provided line lock function.
Features
• Support Ye, Cyan, Magenta, Green complementary color filter CCD sensors for
NTSC : Ai325CA(250K), Ai338CA(380K)
PAL : Ai329CA(290K), Ai344CA(440K)
• Flexible Color Adjustment.
• Digital Noise Reduction.
• High performance AWB (5 set linear matrix).
• IRIS coexists with AES and AGC.
• Day or Night notice output.
• Timing adjustment by 1 ns delay
• White clip / Setup level / Sync level adjustment independent.
• Build-in blemish compensation circuit to store the data in EEPROM,
the blemish pixel can up to 176 pixels.
• Programmable pull-up / pull-down GPIO and DVIO pin.
• Horizontal resolution up to 500 TVL
• Video drive for IRIS lens is possible by simple drive circuit
even no CCD signal pin (CCDLEVEL or Mon_out) from AFE.
• Hi-speed AE.
• Support external EEPROM to store parameter.
• Build-in auto white balance control.
• Build-in auto exposure control.
• Build-in backlight compensation.
• Build-in 10bit digital to analog converter.
• Build-in mirror function.
• Support NTSC/PAL analog composite video output.
• Build-in timing generator for vertical driver and CDS/AGC/ADC peripheral chips.
• Single 3.3V power supply. (Horizontal drive pins can be 3.3V/5V)
• Support GPIO pin Define function.
• Programmable CCD Timing and Driving Current.
• Support Digital Line Lock function.
• LQFP-80 (10x10mm ; 0.4mm pin pitch)
