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.
