Linear video processing encompasses many components related to the capturing and displaying of video signals. The TDA19989BET/C1,518 is a linear video processing integrated circuit (IC) developed by NXP Semiconductors, introduced in 2018.

The TDA19989BET/C1,518 is part of the TDA19989 family of chips, and is a single-channel, 21-bit digital-to-analog converter (DAC) designed for use in LCD and digital signage displays. It features a voltage output range of 1.8V to 3.3V, a 3V-compliant reference voltage, and a bandwidth of 48kHz. Additionally, it offers unique features such as adjustable offset and gain, programmable gain control, and selectable current output stages.

The TDA19989BET/C1,518 is used for a variety of linear video processing applications. It can be used for general-purpose applications such as monitor calibration and display calibration, as well as for advanced applications such as video resolution scaling, video upscaling, and video playback. It is also suitable for video surveillance camera applications, as well as for displays and monitors for industrial, medical, and public display applications.

To understand the TDA19989BET/C1,518’s working principle, one must first understand how linear video signals work. In a digital video signal, data is encoded in the form of an electronic signal, which is made up of a series of binary ones and zeros (also known as a “bit stream”). As these binary ones and zeros represent the values of the original picture, these values must then be converted back into an analog signal, so that they can be properly displayed on a monitor or TV. This is where the TDA19989BET/C1,518 comes in.

The TDA19989BET/C1,518 uses a technique known as delta-sigma modulation to convert the digital data in the bitstream into an analog signal. Delta-sigma modulation is a type of digital-to-analog conversion that involves sampling the input signal and then applying it to an integrator, which then converts the signal into an analog value. By using this technique, the TDA19989BET/C1,518 can take a digital signal and output an analog signal that can be used to drive an LCD or digital signage display.

The TDA19989BET/C1,518 also features several other features that make it a versatile and efficient chip for linear video signal processing. It can be used in either single-supply or dual-supply applications, and it offers built-in power saving modes. Additionally, the chip offers a wide range of programming options, allowing users to adjust parameters such as offset and gain, as well as selectable current output stages.

These features, combined with its high resolution and fast response time, make the TDA19989BET/C1,518 an ideal choice for many linear video processing applications. Whether it is used for monitoring, display calibration, or advanced video upscaling and playback, the TDA19989BET/C1,518 is a powerful and reliable option for anyone looking to add linear video processing to their setup.
