General Description

The MAX4886 high-speed analog switch is ideal for

HDMI/DVI switching applications, permitting 2:1 or 1:2

switching. The MAX4886 contains four differential pairs

of 1:2 or 2:1 switches for RGB and clocking signals.

The MAX4886 connects either one monitor to one of

two digital video signals, or one HDMI/DVI source to

one of two loads (sink).

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.
