Circuits from the Lab™ reference circuits from Analog Devices have been designed and built by Analog Devices engineers. Standard engineering practices have been employed in the design and construction of each circuit, and their function and performance have been tested and verified in a lab environment at room temperature.
This document presents a reference circuit design using two ADV7612 Dual Port Xpressview 225 MHz HDMI Receivers to create a quad-input fast switching HDMI receiver. The circuit allows for multiplexing four HDMI inputs over a common video and audio bus, utilizing an ADV7511 Transmitter as the backend device. It is designed to operate over an extended industrial temperature range of -40°C to +85°C.
| Temperature Range | -40°C to +85°C |
|---|---|
| HDMI Input Speed | up to 225 MHz |
| Pixel Clock (1080p60) | 148.5 MHz |
| Pixel Clock (UXGA) | 162 MHz |
| Series Resistor (Data Lines) | 51 Ω |
The circuit supports four multiplexed HDMI inputs by connecting two ADV7612 devices in parallel.
The circuit operates over the extended industrial temperature range of -40°C to +85°C.
The LLC line should be terminated with a symmetrical termination of 150 Ω to +3.3 V and 150 Ω to GND.
