TDA9984AHW/HTQ,551 application field and working principle

Linear - Video Processing

The TDA9984AHW/HTQ,551 is a semiconductor device from NXP Semiconductors that provides analog video signal processing for linear applications. The device provides all of the necessary functions for performing analog video signal processing, including anti-aliasing, de-interlacing, video filter, and video input selection, as well as line-level control of the analog video signal chain.

Features

The TDA9984AHW/HTQ,551 features integrated anti-aliasing, de-interlacing, video filter, and video input selection capabilities. It also features a direct-connected flat panel controller with read-only capability, which can be used to assist in protecting against opto-acrobatic and gelling signals. The device also has power saving features such as dynamic power management and programmable suspension modes, which allow the device to adapt to changing load conditions and reduce power consumption. Additionally, the device has a robust industrial design that is both shock and EMI tolerant, making it suitable for a wide range of industrial applications.

Application Fields

The TDA9984AHW/HTQ,551 is ideal for a wide range of linear video processing applications. It is suitable for applications such as medical imaging, video surveillance, broadcast video, video editing, and video equipment for surveillance and security purposes. Additionally, the device is an excellent choice for automotive applications that require analog video processing, such as in-vehicle infotainment, audio, and video systems.

Working Principle

The TDA9984AHW/HTQ,551 utilizes a digital signal processing approach to analog video signal processing. At its core, the device consists of three primary components: an analog-to-digital converter (ADC), an analog video processing and control unit (AVPCU) and a digital-to-analog converter (DAC). The ADC is used to convert the analog video signal into a digital signal, which is then passed to the AVPCU. The AVPCU acts as the core of the device and is responsible for a number of signal processing tasks, such as anti-aliasing, de-interlacing and video filter selection. The digitally-processed signal is then converted back to an analog signal and output by the DAC. The TDA9984AHW/HTQ,551 also includes a slew of line-level control logic which can be used to provide additional control over the analog video signal chain. This includes configurable input selection, video system/channel assignment, video filter selection, as well as anti-aliasing and de-interlacing. Additionally, the device also provides a number of power saving features, such as dynamic power management and programmable suspension modes, which allow the device to adapt to changing load conditions, further reducing power consumption. The device’s industrial design makes it suitable for a wide range of applications in the linear video processing domain. Therefore, the TDA9984AHW/HTQ,551 is an excellent choice for a wide range of linear video processing applications.
