PI3PCIE2215
3.3V, PCI Express® 1-lane,
2:1 Mux/DeMux Switch
Description
Pericom Semiconductor’s PI3PCIE2215 is a 4 to 2 differential chan-
nel multiplexer/demultiplexer switch.The PI3PCIE family of switch
solutions is fully compliant with PCIe® signals at 5.0Gbps. Due to
its low bit-to-bit skew, high channel-to-channel noise isolation and
high bandwidth, this product is ideal for PCI Express switching.
Application
Switch a PCI Express® lane output between two PCI Express lane
inputs

passed through to the AOa+, AOa- pin respectively when
SEL=0. Signal is passed through to the AOb+, AOb- pin
respectively when SEL = 1.
Differential analog pass-through output. Signal from AI+
and AI- is passed through AOa+ and AOa- respectively
when SEL=0.
Differential analog pass-through output. Signal from AI+
and AI- is passed through AOa+ and AOa- respectively
when SEL=1.
Differential input pair from PCIE signal source. Signal is
passed through to the BOa+, BOa- pin respectively when
SEL=0. Signal is passed through to the BOb+, BOb- pin
respectively when SEL = 1.
Differential analog pass-through output. Signal from BI+
and BI- is passed through BOa+ and BOa- respectively
when SEL=0.
Differential analog pass-through output. Signal from BI+
and BI- is passed through BOb+ and BOb- respectively
when SEL=1.
Ground
