**ADV7622BSTZ-RL: A Comprehensive Integrated 4:1 HDMI/DVI Receiver with Xpressview™ Fast Switching**

The **ADV7622BSTZ-RL** is a highly integrated quad-input HDMI/DVI receiver designed to meet the demanding requirements of modern video switching applications. This advanced component serves as a **complete 4:1 HDMI/DVI switch solution**, integrating critical functionalities that were traditionally handled by multiple discrete chips. Its primary role is to receive digital audio/video content from up to four separate HDMI or DVI sources, process it, and output it to a single display sink, such as a television, monitor, or projector.

A cornerstone feature of the ADV7622BSTZ-RL is its **proprietary Xpressview™ fast-switching technology**. This innovative capability addresses a common user frustration: the significant delay experienced when switching between different HDMI sources. Conventional receivers require a full re-initialization of the HDCP (High-bandwidth Digital Content Protection) handshake with each input change, a process that can take several seconds. **Xpressview™ dramatically reduces switching time** by maintaining the necessary HDCP state information for all connected inputs, enabling near-instantaneous source changes. This provides a seamless and responsive user experience, crucial for commercial applications like video conferencing systems, digital signage, and high-end home theater setups.

Beyond its switching prowess, the device is a powerhouse of integrated signal management. It features four HDMI receivers that support all mandatory and common 3D TV formats, deep color, and high-bit-rate audio formats. Each input is equipped with **advanced adaptive cable equalizers** that compensate for signal degradation over long cable runs, ensuring robust and reliable data recovery. On the output side, it includes two HDMI transmitters, allowing for simultaneous output to two displays or for daisy-chaining devices.

The internal structure incorporates a **high-performance video processor** capable of scaling and performing aspect ratio control, converting content to match the native resolution of the display. Furthermore, it integrates an **Audio Processor** and an **Audio Sample Rate Converter** to handle various audio streams, including the extraction of embedded audio from HDMI for output to external audio systems.

Housed in a compact 100-lead LQFP package, the ADV7622BSTZ-RL is engineered for space-constrained designs. Its low-power architecture makes it suitable for a wide range of consumer and professional AV equipment. By combining a quad-input HDMI/DVI switch, cable equalizers, an audio processor, and video processing into a single chip, it significantly reduces system complexity, bill-of-materials cost, and design time for engineers.

**ICGOOFind:** The ADV7622BSTZ-RL stands out as a superior integrated solution for video distribution, **merging four HDMI/DVI inputs with advanced processing and groundbreaking Xpressview™ fast-switching technology**. It is the ideal component for designing efficient, high-performance, and user-friendly systems that require seamless multi-source switching.
