High-speed video switch supports latest standards

Diodes Incorporated has announced the PI3WVR41310, a 13.5Gbps high-speed video switch. The device allows increased resolution and refresh rates in next-generation commercial displays, gaming monitors, docking stations, video-matrix switches, and embedded applications.

The four-lane video switch operates as a 3:1 multiplexer or 1:3 demultiplexer. With insertion loss of -1.8dB at 13.5Gbps and a -3dB bandwidth of 10GHz, the switch supports connections such as DisplayPort 2.1 up to the ultra-high bit rate UHBR13.5 specification, including HDMI 2.1 and other emerging and proprietary standards.

The device also enables a wide signal-voltage range, with a common-mode voltage from 0V to the supply rail, which allows multi-standard, DC-coupled operations. By eradicating AC-coupling capacitors, DC coupling saves space in densely populated PCB designs and improves signal integrity. Developed for use in high-speed video signalling applications, the device also provides low signal-return loss with low channel-to-channel crosstalk, low off-channel isolation, and low bit-to-bit skew.

To enable proper configuration and communication between connected devices, there are dedicated DDC/AUX pins and HPD pins, allowing equipment to automatically recognise when connections are made.

The device is supplied in a 52-pin leadless package with a 3.5mm x 9mm footprint that saves space and aids lower PCB costs.
