The ADV7182A has the same pinout and is software compatible with theADV7182.The ADV7182A is a versatile, one chip, multiformat video decoder that automatically detects standard analog baseband video signals and converts them into YCbCr 4:2:2 component video data streams.The analog input of the ADV7182A features a single, 10-bit analog-to-digital converter (ADC) and an on-chip differential to single-ended converter to accommodate direct connection of differential, pseudo differential, or single-ended CVBS without the need for external amplifier circuitry.The standard definition processor (SDP) on the ADV7182A automatically detects NTSC, PAL, and SECAM standards in the form of CVBS (composite), S-Video (Y/C), and YPrPb (component). The analog video is converted into a 4:2:2 component video data stream that is compatible with the 8-bit ITU-R BT.656 interface standard. External synchronization timing signals are also available.The ADV7182A is provided in a space-saving, LFCSP, surface- mount, RoHS compliant package. It is offered in an automotive grade rated over the −40°C to +105°C temperature range, as well as a −40°C to +85°C industrial temperature range, making the device ideal for automotive, industrial, and consumer applications.The ADV7182A must be configured in accordance with the I2C writes provided in the evaluation board script files.ApplicationsAdvanced driver assistanceAutomotive infotainmentDVRs for video securityMedia players

The ADV7186 is a high performance, single chip, multiformat video decoder and processor with integrated LVDS Tx and LVDS Rx. The ADV7186 analog front end comprises single high speed, 10-bit ADC that digitizes the analog video signal. The ADV7186 analog front end supports input resolutions up to SVGA (800 × 600 at 60 Hz). The ADV7186 has 48 pixel pins, of which 24 are inputs and 24 are outputs.The ADV7186BBCZ-T contains features identical to the ADV7186BBCZ apart from having a TCON (LCD timing control) output in place of the LVDS Tx output and not supporting an LVDS Rx.The ADV7186BBCZ-TL is a reduced function version of the ADV7186BBCZ-T and does not support external SDRAM. All other functionality is identical to that of the ADV7186BBCZ-T.The multiformat decoder contains a standard definition processor (SDP) supporting the conversion of PAL, NTSC, and SECAM standards in the form of a composite or an S-Video input signal into a digital ITU-R BT.656 format.The ADV7186 contains one main component processor (CP) that processes YPbPr and RGB component formats, including RGB graphics. The ADV7186 analog front end supports the decoding of these RGB/YPbPr video signals into a digital YCbCr or RGB pixel output stream. The support for component video includes 525i, 525p, 625i, 625p, 720p, and 1080i standards while QVGA to SVGA graphic rates are supported.The CP core can also process video with resolutions up to WXGA from the input pixel pins or LVDS Rx.The video signal processor can perform edge-adaptive intrafield de-interlacing, ensuring excellent performance on low angle edges as well as antiflickering filtering. The video signal processor allows scaling between common video resolutions, enabling up to WXGA output (the output frame rate is always equal to the input field/frame rate). ACE offers improved visual detail. Flip/mirror capability allows for compensation of different camera mounting orientations.An independent BT.656 channel allows access to the output of the SD and CP cores. Simultaneously, the output pixel bus or LVDS Tx can drive out video data that has been received via the input pixel bus or the LVDS Rx bus. In the case of the ADV7186BBCZ only, the pins used for the BT.656 channel are shared with the external memory interface. In the case of the ADV7186BBCZ-T and ADV7186BBCZ-TL, the pins used for the independent BT.656 channel are shared with both the external memory interface and the TCON[10:0] pins, leaving it to the user to select the preferred option.The ADV7186 can accept up to two layers of overlay on the main picture. The sources of this overlay can be the TTL/LVDS Rx and/or the EEPROM bitmap or the low cost overlay. These layers can be overlaid on the input video stream using alpha blending and chroma keying.In addition to the full overlay functionality, the ADV7186 supports a low cost overlay function that requires no external memory. This feature allows overlay on a predefined section of the display using one foreground and one background color, allowing a warning or information banner to be displayed over the viewed video.The LCD controller function includes TCON signals enabling the ADV7186BBCZ-T and ADV7186BBCZ-TL only to drive glass-only panels. PWM backlight control enables a programmable dimming ratio. To compensate for nonlinearity in the video system, the ADV7186 allows a 32-point gamma correction curve to be applied independently on each output channel (RGB or YCbCr).Where boot time is critical, the ADV7186 has a hardware self-configurable fastboot feature, enabling video to be displayed directly after power-up. Bitmaps stored in the EEPROM can also be loaded and displayed on power-up.The ADV7186W models are automotive qualified.APPLICATIONSNavigation radios and infotainment head unitsCentral console and rear seat monitorsParking guide and ADAS vision systemsPico and mini projectorsIndustrial monitors and displays

The ADV7188 integrated video decoder automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into 4:2:2 component video data compatible with 20-/16-/10-/8-bit CCIR 601/CCIR 656.The advanced, highly flexible digital output interface enables performance video decoding and conversion in line-locked, clock-based systems. This makes the device ideally suited for a broad range of applications with diverse analog video characteristics, including tape-based sources, broadcast sources, security and surveillance cameras, and professional systems.The accurate 12-bit ADC provides professional quality video performance and is unmatched. This allows true 10-bit resolution in the 10-bit output mode.The 12 analog input channels accept standard composite, S-video, and component video signals in an extensive number of combinations.AGC and clamp-restore circuitry allow an input video signal peak-to-peak range of 0.5 V to 1.6 V. Alternatively, these can be bypassed for manual settings.The fixed 54 MHz clocking of the ADCs and datapath for all modes allows very precise, accurate sampling and digital filtering. The line-locked clock output allows the output data rate, timing signals, and output clock signals to be synchronous, asynchronous, or line locked even with ±5% variation in line length. The output control signals allow glueless interface connections in most applications. The ADV7188 modes are set up over a 2-wire, serial, bidirectional port (I2C compatible).SCART and overlay functionality are enabled by the ability of the ADV7188 to process CVBS and standard definition RGB signals simultaneously. Signal mixing is controlled by the fast blank pin. The ADV7188 is fabricated in a 3.3 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. It is packaged in a small, Pb-free, 80-lead LQFP.APPLICATIONSHigh end DVD recordersVideo projectorsHDD-based PVRs/DVDRsLCD TVsSet-top boxesProfessional video productsAVR receiver
