| PI2PCIE412-D Enhanced, 1.8V, PCI Express Compliant, 4-Differential Channel, 2:1 Mux/DeMux Switch, w/ Single Enable Features * * * * * * * * * 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 Low Off Isolation: -65dB@10 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) Description 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.
