PI2PCIE412-D

Enhanced, 1.8V, PCI Express Compliant,

4-Differential Channel, 2:1 Mux/DeMux Switch,

w/ Single Enable

Features

Description

• 4 Differential Channel, 2:1 Mux/DeMux

• PCI Express signal compliance

• Low Bit-to-Bit Skew , 10ps max (between '+' and '-' bits)

• Low Crosstalk: -65dB@10 MHz

Pericom Semiconductor’s PI2PCIE412-D is an 8 to 4 differential

channel multiplexer/demultiplexer switch. This solution can

switch 2 full PCI Express lanes to one of two locations. Using

a unique design technique, Pericom has been able to minimize

the impedance of the switch such that the attenuation observed

through the switch is negligible. The unique design technique

also offers a layout targeted for PCI Express signals, which

minimizes the channel to channel skew as well as channel to

channel crosstalk as required by the PCI Express speciﬁcation.

• Low Off Isolation: -65dB@10 MHz

• V Operating Range: +1.5V to +2.0V

• ESD Tolerance: 8kV HBM I/O; 2kV HBM select pin

• Low channel-to-channel skew, 35ps max

• Packaging (Pb-free & Green):

– 42-contact, TQFN (ZH42)

Application

Switch a PCI-Express lane output between two PCI Express lane

inputs.
