Linear video processing transports images and optics into digital form while preserving the spatial detail and visual motion characteristics of the signals. In today’s world, it enables applications such as streaming media, autonomous navigation, facial recognition, surveillance and virtual reality. The AD9928BBCZ mixed signal processing application field and working principle is an example of linear video processing that is designed to extend the capabilities of digital video processing and improve signal quality.

The AD9928BBCZ mixed signal processor is a commercial grade chip designed to process linear video signals and extract information for various purposes. The device functions as an analog-to-digital converter (ADC) to convert linear video input signals into digital data, and a digital-to-analog converter (DAC) to convert digital data into linear video output signals. The device has a variable analog bandwidth, so it can process standard video formats up to 4K/8K UHD resolutions or other types of linear signals. This enables a wide range of applications, from video and HDTV broadcast to video conferencing, medical imaging, virtual reality, robotics and security cameras.

The processor is based on a charge-domain, multiplexed architecture that allows more analog signal paths to be used than traditional analog-to-digital conversion platforms. The device operates at sampling frequencies up to 250MHz, and each channel supports up to 16 bits of resolution. This makes it ideal for high-resolution applications and enables video to be processed at high frame rates.

The AD9928BBCZ includes a wide range of video processing functions. It has an adjustable gain and offset control, an antialiasing filter, and a low-pass filter. The adaptive HDR capability supports a wide range of dynamic range values, while motion and motion vector interpolation reduce motion artefacts. The integrated wide range of noise reduction features help reduce noise and unwanted artifacts, while improving signal quality. In addition, the device has built-in color space conversion, colorimetry and gamut mapping, enabling accurate colors and colorspace matching. Additionally, the system supports full range of HDR formats, including HLG and PQ.

The AD9928BBCZ also features a range of degradation and error correction features, such as de-noise, edge and frequency equalisation, post-proportional correction, noise modeling and test pattern generation. Additionally, the device includes a digital interface such as I2C, LVDS and SPI. This allows it to be connected to video extenders, video switchers, routers and cameras.

The AD9928BBCZ mixed signal processing application field and working principle is an innovative example of linear video processing technology, designed to facilitate high-resolution video applications across a wide range of formats and resolutions. The device offers a wide range of advanced video processing functions, such as adaptive HDR, colorimetry and noise reduction, as well as error correction and test pattern generation. The advanced performance and integrated digital interface make the AD9928BBCZ the ideal choice for a wide range of video applications.
