PI2PCIE412-D Enhanced, 1.8V, PCI Express Compliant, 4-Differential Channel, 2:1 Mux/DeMux Switch, w/ Single Enable • 4 Differential Channel, 2:1 Mux/DeMux • PCI Express signal compliance • Low Bit-to-Bit Skew , 10ps max between '+' and '-' bits • Low Crosstalk MHz • Low Off Isolation MHz • VCC 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 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. Application Switch a PCI-Express lane output between two PCI Express lane inputs.
