ADI ADV7182AWBCPZ 10-Bit SDTV Video Decoder With Differential Inputs

Shenzhen Mingjiada Electronics Co., Ltd., as a professional supplier of electronic components, now offers the original ADV7182AWBCPZ 10-bit SDTV video decoder from ADI. This chip is a high-performance, multi-format video decoder specifically designed for applications requiring the conversion of analog video signals into digital video streams.

【Product Overview Of ADV7182AWBCPZ】

ADV7182AWBCPZ 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 ADV7182AWBCPZ 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 ADV7182AWBCPZ 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 ADV7182AWBCPZ is provided in a space-saving, LFCSP, surfacemount, 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.

【Core Features and Performance Advantages Of ADV7182AWBCPZ】

ADV7182AWBCPZ is a powerful video decoder chip whose core value lies in its ability to automatically detect and convert global mainstream analog television standard signals.  

ADV7182AWBCPZ supports NTSC, PAL, and SECAM color demodulation standards, converting analog baseband video signals compatible with these standards into 4:2:2 component digital video data streams. The output digital video stream complies with the 8-bit ITU-R BT.656 interface standard, greatly facilitating connectivity with downstream digital processing equipment.

In terms of analog signal processing capabilities, the ADV7182AWBCPZ demonstrates high flexibility and robustness:

Input flexibility: Accepts single-ended, pseudo-differential, and fully differential composite video signals, as well as S-Video (Y/C) and YPbPr component video signals.

Interference resistance: When used with an external resistor voltage divider, it provides a common-mode input range solution of up to 4V, effectively eliminating large common-mode transients on video lines. Its excellent common-mode rejection (CMR) capability achieves performance of up to 80dB without the need for external amplifier circuits.

Built-in enhancement features: Integrated with a 5-line adaptive comb filter and CTI/DNR (color transient improvement/noise reduction) video enhancement features, effectively improving output image quality.

ADV7182AWBCPZ chip incorporates a 10-bit analog-to-digital converter (ADC) and provides different oversampling capabilities based on the input signal type: 4x oversampling for composite video, 2x oversampling for Y/C mode, and 2x oversampling for YPrPb. This ensures professional-quality video performance.

ADV7182AWBCPZ also features adaptive digital line length tracking, signal processing, and enhanced first-in-first-out management, providing time base correction functionality and enabling fast video switching.

【ADV7182AWBCPZ Application Areas】

Automotive infotainment systems: Requiring high reliability and environmental adaptability, the chip's wide common-mode input range, strong interference resistance, and AEC-Q100 qualification enable it to withstand the complex environments of automotive electronics.

Video security-enabled digital video recorders: Capable of processing analog surveillance video signals from multiple sources and formats, converting them into standard digital signals for encoding and storage.

Media players: Used in modern media playback and conversion devices that require compatibility with traditional analog video input devices.
