MAX4886ETO+T

Video Processing Overview

The MAX4886ETO+T is a quad, high-speed HDMI/DVI 2:1 digital video switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.0V to +3.6V power supply and features four differential pairs of 1:2 or 2:1 switches for RGB and clocking signals. The device utilizes an nFET architecture with an internal charge pump, providing an 8Ω typical on-resistance and 2.5pF on-capacitance. Key electrical parameters include a 2.6GHz bandwidth, 700µA quiescent current, and -58dB off-isolation at 50MHz. It is housed in a 42-pin TQFN-EP package.

Video Processing Feature Summary

• Integrates four differential pairs of 1:2 or 2:1 switches designed for routing RGB and clocking signals in HDMI/DVI applications.
• Employs an nFET architecture with an internal charge pump to achieve extremely low capacitance and on-resistance for excellent return loss.
• Features an efficient internal charge-pump design that offers very low quiescent current suitable for power-sensitive notebook designs.

Video Processing Applications

• HDTV Monitors/Receivers
• Video Projectors
• Notebook Computers
• Digital HDTV Switch Boxes/Tuners
• Servers/Routers with DVI Interfaces

Video Processing FAQ

What is the maximum continuous current through any switch?

The maximum continuous current through any switch is ±120mA.

How does the SEL input control the switch?

The SEL logic input controls the switch connection; setting SEL to 0 connects COM_ to NC_, while setting it to 1 connects COM_ to NO_.
