1 / 9 page  1 PS8788B 01/23/06 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.
