Description
The STMUX3040 is a differential Single Pole
Double Throw (SPDT) 2 to 1, low Ron, bi-
directional signal switch designed for PCIe
signaling.
It is designed for very low cross-talk, low bit-to-bit
skew, high channel-to-channel noise isolation and
low I/O capacitance. The switch offers very little or
practically no attenuation of the high speed
signals at the outputs, thus preserving the signal
integrity to pass stringent requirements.
