DATA SHORT To request the full datasheet, please visit: ISL79985 or ISL79986 ISL79985, ISL79986 FN8851 Rev 2.00 June 24, 2016 4-Channel Differential Input Video Decoder with MIPI-CSI2/BT.656 Output for Around View Applications Features The ISL79985, ISL79986 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. 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. Analog Video Decoder • Software selectable analog input control allows for combinations of single-ended CVBS and differential CVBS • 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 Applications • Digital subcarrier PLL for accurate color decoding • 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 AFE CLKO/ MPP[1] CSC ADC AGC CSC 4H COMB VIDEO DE C ACA AA FILTER ACA VIN1A MPP[0] VIN1B DEC_CH REGFILE DIAG1 AA FILTER 4H COMB VIDEO DE C ADC AGC DEC_CH DIAG3 VIN4A VIN4B AA FILTER DEC_CH DIAG4 PLL XTI XTO OSC PD SHORT DETECTION MIP ID1 REGFILE I2C INTE RFACE SCLK RSTB MIP ID0 REGFILE 4H COMB VIDEO DE C ADC AGC CSC 4H COMB VIDEO DE C ADC AGC CSC AA FILTER ACA VIN3B ACA VIN3A MIP IC REGFILE IRQ DIAG2 REGFILE SDAT DEC_CH MIP I CSI AND DPHY VIN2B FIFO CONTROL LINE INTERLEAVING ENGINE VIN2A FIGURE 1.
