Design requirements of the MIPI standard must be followed. Supply pin decoupling capacitors of 2.2 µF and 100 nF are recommended for best performance. The TMUX646 has internal 6-MΩ pulldown resistors on SEL and OE. The pulldown on these pins ensure that the digital remains in a non-floating state during system power-up to prevent shoot through current spikes and an unknown switch status. By default the switch will power up enabled and with the A path selected until driven externally by the processor.
