4-Channel Differential Input Video Decoder with MIPI-CSI2/BT.656 Output for

Around View Applications

The ISL79985, ISL79986 integrates four high quality

Features

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

Analog Video Decoder

• Software selectable analog input control allows for

combinations of single-ended CVBS and differential CVBS

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.

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 make the ISL79985,

ISL79986 an ideal solution for demanding automotive around

view applications.

• Integrated four video analog anti-aliasing filters and 10-bit

CMOS ADCs with differential and single-ended inputs

• Fully programmable static gain or automatic gain control for

the Y-channel

• Programmable white peak control for the Y-channel

• 4-H adaptive comb filter Y/C separation

• PAL delay line for color phase error correction

• Digital subcarrier PLL for accurate color decoding

Applications

• Automotive surround view

• Digital horizontal PLL for synchronization processing and

pixel sampling

• Advanced synchronization processing and sync detection for

handling non-standard and weak signal

• Automatic color control and color killer

• Chroma IF compensation

• Programmable output cropping
