STMUX3040 Datasheet Octal SPDT high bandwidth signal switch

Manufacturer: STMicroelectronics

General Description

The STMUX3040 is a differential Single Pole Double Throw (SPDT) 2 to 1, low Ron, bidirectional 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.
