Dalian Da Youshang Group Launches HDMI 2.0 Bidirectional Switcher Solution Based on Diodes Products

The HDMI 2.0 two-way switcher solution based on PI3WVR12412 does not require an external power supply, which can reduce the placement of desktop cables and provide a refreshing and tidy entertainment office scene. As a 2-port HDMI two-way switcher, this solution uses HDMI cables connected to input devices to provide power, thus eliminating the need for a power supply port. And the HDMI cable can also be used for audio and video transmission, so there is no need for external audio.

On December 16, 2021, the leading distributor of semiconductor components dedicated to the Asia-Pacific market, Grand United Holdings, announced that its subsidiary Youshang has launched an HDMI2.0 two-way switcher solution based on Diodes PI3WVR12412 chip.

As a new generation of digital audio and video standard interface, HDMI is widely used in home theaters, conference systems and other fields. In this context, products that support HDMI interface input and output are becoming more popular. However, most Display devices currently on the market usually only provide one set of HDMI input terminals. Therefore, users must continuously plug and unplug cables to connect different products. The HDMI switch application can connect different HDMI input devices to a single HDMI display device. Users can easily switch various connected digital devices through an infrared remote control or front panel buttons. Dalian University Friends is still based on the Diodes PI3WVR12412 chip HDMI 2.0 two-way switch solution, which can greatly improve the convenience of operation.

Founded in 1966, Diodes is mainly engaged in the manufacture and supply of discrete, logic and analog semiconductor products. Its products are widely used in the industrial, communications and automotive markets. The PI3WVR12412 used in this solution is a multi-standard video switch with a wide voltage range under Diodes. It supports DisplayPort™ 1.2 and HDMI 1.4 standards, and can transmit peak-to-peak differential high-speed signals up to 1.2V, with a common-mode voltage range of 0 to 3.4V. This allows DC-coupled multi-standard operation and eliminates AC-coupling capacitors, which can save PCB design space and improve its signal integrity.
