PI2PCIE2422 PCI Express Gen II Compliant, 8-Differential Channel Switch with 8:4 Mux/DeMux Option Features Description • • • • • • • • Pericom semiconductor’s PI2PCIE2422 is an 8 to 4 channel differential multiplexer/demultiplexer featuring 8-channel passthrough. It supports two full PCI Express lanes at 5.0Gbps Gen II performance. 8 Differential Channel SPST switch with Mux/DeMux option PCI Express Gen II performance Low Bit-to-Bit Skew: 10ps (between +/- signals) Low Crosstalk: -15dB @ 3.0 GHz Low Off Isolation: -26db @ 3.0 GHz VDD Operating Range: +1.4V to +1.8V ±10% ESD Tolerance >2kV HBM Packaging (Pb-free & Green): 42-contact TQFN (ZH42) With the select control input low Port A connects to Port B, and Port C connects to port D for an 8-channel differential pass-though. When the select control input is high Port A connects to Port D, and Port B and Port C are in a high-impedance state. The mux/demux function is between Port A and Ports B or D as determined by the select input control.
