PI3PCIE3422ZHEX

Analog Switches - Special Purpose Overview

The PI3PCIE3422ZHEX is a 3.3V, PCI Express 3.0 compliant differential multiplexer and demultiplexer manufactured by Diodes Incorporated. It features an 8-channel pass-through architecture supporting two full PCIe lanes at 8.0Gbps data rates. The device provides configurable routing between Port A and Ports B or D via a single SEL control input, while maintaining low bit-to-bit skew of 10ps maximum and crosstalk below -50dB at 4.0GHz. It operates within a VDD range of 3.0V to 3.6V and utilizes a 42-contact TQFN package.

Analog Switches - Special Purpose Feature Summary

• Supports bi-directional operation with selectable mux/demux functionality for flexible signal routing
• Maintains high signal integrity through minimized channel-to-channel skew and low insertion loss
• Features active output enable control allowing all I/O pins to enter a high-impedance state

Analog Switches - Special Purpose Applications

• PCI Express 3.0 system interconnects requiring lane switching
• High-speed differential signal routing in server and storage platforms
• Signal path configuration in complex motherboard topologies

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type. The 'E' designation indicates lead-free and green material compliance, while the trailing 'X' specifies tape and reel delivery format. Confirm that the component meets RoHS standards required for your assembly process before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring an 8-channel differential switch with PCIe 3.0 performance capabilities. Ensure the design accommodates the 42-contact TQFN footprint and the 3.3V power supply requirements. Verify that the application logic correctly drives the SEL and OE# pins to achieve the desired bypass or muxing states.

Analog Switches - Special Purpose Part Context
