Interface bridges are an integral part of modern embedded systems. This article is about the ADV7391WBCPZ-RL, an extremely versatile encoder-decoder that is used as an interface bridge between video and audio-processing systems. The ADV7391WBCPZ-RL is a high-performance, low-power, mixed-signal device.

Overview

The ADV7391WBCPZ-RL is a highly integrated mixed-signal device designed for use in video and audio-processing systems. It is an extremely versatile encoder-decoder that is used as an interface bridge between video and audio-processing systems. The ADV7391WBCPZ-RL includes an 8-bit parallel video port, a 2-bit LVDS audio-processing port, and a 2-bit LVDS audio-output port. It also has a Serial Video Interface (SVI) for 8- and 10-bit video processing. It has an integrated low phase-noise PLL and supports HDTV/SDTV/DTV resolution standards such as 1080p/720p/480p/576p/1080i/720i/480i/576i.

The ADV7391WBCPZ-RL features a HDCP 2.2 compliant protocol and is available in a 7x7-mm, 48-pin LLP package. It is designed to meet the stringent requirements of low-power video-processing applications.

Application Field

The ADV7391WBCPZ-RL is used mainly as an interface bridge between video and audio-processing systems. This device is able to bridge the analog/digital distinctions in modern systems, offering a solution to customers requiring high-quality interface solutions while leveraging the efficiency and cost-efficiencies of digital video and audio processing systems. This device can be used in a wide range of applications, including digital video-security systems, digital signage, automotive infotainment systems, and PC-based video applications.

Working Principle

The ADV7391WBCPZ-RL works in two main modes. In the first, it acts as an encoder, converting the incoming parallel video stream into a serial video stream, which is then formatted into an HDTV/DTV stream. In the second mode, it acts as a decoder, converting the serial video stream back into a parallel video stream, which is then sent to the display device. The ADV7391WBCPZ-RL also features an integrated low phase-noise PLL which works to reduce the amount of jitter in the signal stream.

The ADV7391WBCPZ-RL also includes a 2-bit LVDS audio-processing port, which allows it to be used as an audio-processing interface. The ADV7391WBCPZ-RL is capable of producing up to 24-bit audio, with a maximum sample rate of 96KHz. The device supports multiple output formats, including S/PDIF, HDMI, and IEC61937 (8 or 16 PCM channels).

Conclusion

The ADV7391WBCPZ-RL is an extremely versatile encoder-decoder that is used as an interface bridge between video and audio-processing systems. Its high performance and low power consumption make it perfect for use in a variety of applications, such as digital video-security systems, digital signage, automotive infotainment systems, and PC-based video applications. The integrated low-phase-noise PLL helps to reduce the amount of jitter in the signal stream, and the device supports multiple audio formats. This makes the ADV7391WBCPZ-RL an ideal solution for customers looking for high-quality interface solutions.
