MAX4886
Quad, High-Speed HDMI/DVI 2:1 Digital Video Switch
High-Speed Analog Switch Designed for HDMI/DVI Digital Video Switching

MyMaxim SubscriptionsProduct Details
The MAX4886 set of differential switches is based on an nFET architecture with internal charge pump for gate overdrive. This advanced architecture results in an extremely low capacitance and on-resistance needed for the excellent return loss requirements for digital switching. An efficient internal charge-pump design offers very low quiescent current for power-sensitive notebook designs.
The MAX4886 features 8Ω (typ) on-resistance and 2.5pF on-capacitance switches for routing RGB and CLK video signals. The MAX4886 is a high-frequency companion device to the MAX4929. These two devices combined perform the full 2:1 HDMI/DVI switching function.
The MAX4886 is available in a space-saving, 42-pin, 3.5mm x 9.0mm TQFN package and operates over the extended -40°C to +85°C temperature range.
Key Features
- Single +3.0V to +3.6V Power Supply
- Low On-Resistance (RON): 8Ω (typ)
- Low On-Capacitance (CON): 2.5pF (typ)
- Low Skew: 20ps (typ)
- 700μA Low Supply Current
- 2.6GHz (typ) Ultra-High Bandwidth
- 0.6dB (typ) Ultra-Low Insertion Loss
- High-Frequency Companion Device to MAX4929
- Use MAX4886 and MAX4929 to Form a Complete HDMI/DVI 2:1 Switch
- 42-Pin, 3.5mm x 9.0mm, Space-Saving TQFN

Description
The MAX4886 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that contains two sub circuits, a typical 2:1 HDMI™ switch application (top half), and an eye diagram test circuit (bottom half).
The MAX4886 HDMI application circuit evaluates the MAX4886 high-speed HDMI/DVI™ 2:1 digital video switch, combined with the MAX4929E for lower frequency signals, to provide a full 2:1 HDMI application circuit. The EV kit operates from a 5V DC power supply and provides on-board 3.3V regulation. HDMI input/output connections are also provided to easily interface with HDMI-compatible devices. All signal traces in the HDMI application circuit are 100Ω differential controlled-impedance traces.
A separate test circuit is also provided at the bottom of the MAX4886 EV kit for eye diagram evaluation using SMA connections and 50Ω controlled-impedance traces.
Features
- Self-Powered from HDMI Source
- Optional 5V Power Supply
- Complete 2:1 HDMI Switching Circuit
- Eye Diagram Test Circuit with SMA Input/Output
- HDMI Inputs/Outputs
- Surface-Mount Construction
- Fully Assembled and Tested
