ICs for Video Camera AN2108NFHQ AN2108NFHQ Camera Signal Processing(CDS + AGC + Gamma) n Overview The AN2108NFHQ is a single-chip IC that processes video-signal of CCD-camera and has functions of CDS, AGC, pre-knee and pre-aperture circuits. This CDS cir- cuit is capable of high speed sampling of max. 30 MHz to support high-resolution CCD-camera systems (XGA, SXGA, etc.). AGC and OB level(black level) adjust- ments can be controlled with on-chip 8-bit DAC. n Features

• Capable of high speed sampling of max. 30 MHz
• Capable of controlling OB level at the last output stage
• Capable of switching between 2 modes of pre-knee characteristic
• On-chip DAC(8-it, 15-channel)for adjustment (11-channels for internal and external outputs) n Applications
• Digital still cameras, Camcorders, PC cameras, Moni- toring cameras, CCD camera modules, CCD digital camera systems LQFP048-P-0707 Unit : mm 9.00±0.40 9.00±0.401.70 max. 1.40±0.10 (0.625)(0.625) 0.10±0.10 7.00±0.20 7.00±0.20 (0.75) 36 25 1(0.75) 12 0.20 +0.10 –0.05 1348 0.50 SEATING PLANE (1.00) 0.50±0.20 ( ) : Reference value 0 to 10˚ 0.15 +0.1 –0.0
