Octal SPDT high bandwidth signal switch
Features
■ Supports PCIExpress signaling at 2.5Gbps
■ Supports 3.0Gbps generic data rate
■ Octal SPDT switch to support 2 PCI lanes
■ Low Ron: 5.5Ω typical
■ Internal voltage regulator
■ V
operating range
CC
– 1.65 - 2.0V (Internal regulator bypassed)
– 2.7 - 3.6V (Internal regulator active)
TQFN42
■ Low current consumption: 150µA
■ ESD HBM model : 2kV
Description
■ Channel on capacitance: 6pF typical
■ Switching time speed: 9ns
The STMUX3040 is a differential Single Pole
Double Throw (SPDT) 2 to 1, low Ron, bi-
directional signal switch designed for PCIe
signaling.
■ Near to zero propagation delay: 250ps
■ Bandwidth: -3dB at 1200MHz
■ Low crosstalk: -20dB at 1200MHz
■ Bit to bit skew: 50 ps typical
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.
■ Data and control inputs provide undershoot
clamp diode
■ Wide bandwidth minimizes skew and jitter
■ Hot insertion capable
■ Supports bi-directional operation
■ -40°C to 85°C operating temperature range
Applications
■ Workstation
■ PC and Notebook

Internal voltage regulator
STMUX3040 is integrated with an internal voltage regulator. The voltage regulator is
activated when supply voltage to the Vreg pin is more than 2.7V. If the supply to V is less
reg
than 2.2V, the regulator is bypassed.

Maximum rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
