PI3PCIE3422 3.3V, PCI Express® 3.0 2-Lane, (4-Channel), Differential Mux/Demux with Bypass Features Description ÎÎ8 Differential Channel SPST switch with Mux/DeMux option Pericom semiconductor’s PI3PCIE3422 is an 8 to 4 channel differential multiplexer/demultiplexer featuring 8-channel passthrough. It supports two full PCIe® lanes at 8.0Gbps PCIe® 3.0 performance. ÎÎPCIe® 3.0 performance ÎÎBi-directional operation ÎÎLow Bit-to-Bit Skew: 10ps (between ± signals) ÎÎLow Crosstalk: -50dB @ 4.0GHz (8Gbps) ÎÎLow Off Isolation: With the select control input low Port A connects to Port B, and Port C connects to port D for an 8-channel differential passthough. 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. -21dB @4GHz ÎÎLow Insertion Loss: -1.8dB @ 4.0GHz (8Gbps) ÎÎReturn Loss: -15dB @4GHz ÎÎVDD Operating Range: 3.3V ±10% ÎÎESD Tolerance: 2kV HBM ÎÎPackaging (Pb-free & Green): 42-contact, TQFN (ZH42) Truth Table C0+ C0- A1+ A1C1+ C1- A2+ A2C2+ C2- A3+ A3C3+ C3- All trademarks are property of their respective owners.
