The ISL79985 integrates four high quality NTSC/PAL/SECAM video decoders that convert the analog composite video signal to digital component YCbCr data for automotive applications. Each channel contains a 10-bit ADC that supports single-ended, differential, and pseudo differential composite video inputs, proprietary clamp and gain controllers, thus, utilizes a 4H-comb filter for separating luminance and chrominance to reduce cross noise artifacts. ISL79985 also features integrated short-to-battery and short-to-ground detection, advanced image enhancement capabilities such as the programmable Automatic Contrast Adjustment (ACA), and the MIPI-CSI2/ITU-R BT.656 output interface.

FEATURES
• Software selectable analog input control
• Fully programmable static gain or automatic gain control for the Y-channel
• Digital subcarrier PLL for accurate color decoding
• Digital horizontal PLL for synchronization processing and pixel sampling
• PAL delay line for color phase error correction
• Integrated four video analog anti-aliasing filters and 10-bit CMOS ADCs with differential and single-ended inputs
• Programmable white peak control for the Y-channel
• 4-H adaptive comb filter Y/C separation
• 1k MSRP: $6.00 US
