MAX4886
数据手册.pdf四，高速HDMI / DVI 2 ： 1数字视频开关 Quad, High-Speed HDMI/DVI 2:1 Digital Video Switch
Description
The 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.
