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.
