PI2PCIE2412ZHE

Analog Switches - Special Purpose Overview

The PI2PCIE2412ZHEX is a 1.8V, PCI Express Gen II compliant multiplexer/demultiplexer switch manufactured by Diodes Incorporated (formerly Pericom). It features four differential channels configured as a 2:1 mux/demux, capable of switching two full PCIe lanes to one of two locations at speeds up to 5.0 Gbps. The device operates within a supply voltage range of 1.5V to 1.8V ±10% and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum bit-to-bit skew of 7ps, channel-to-channel skew of 35ps, and a bandwidth of 4.1 GHz. It is housed in a 42-contact TQFN package.

Analog Switches - Special Purpose Feature Summary

• Supports PCI Express Gen II performance with low signal attenuation through unique impedance minimization design techniques.
• Provides low crosstalk (-23dB at 3 GHz) and low off-isolation (-23dB at 3 GHz) to maintain signal integrity.
• Features minimal bit-to-bit skew (max 7ps) and channel-to-channel skew (max 35ps) for precise timing alignment.

Analog Switches - Special Purpose Applications

• Routing of PCI-Express Gen 2 signals with low signal attenuation.
• Switching two full PCI Express Gen 2 lanes between two distinct locations.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The 'E' suffix indicates Pb-free and Green packaging compliance, while the 'X' suffix denotes tape and reel packaging configuration. Confirm that the required quantity matches the specified reel size to ensure proper handling and storage conditions are met during acquisition.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring high-speed differential signal routing compliant with PCI Express Gen II standards. Ensure the system power supply strictly adheres to the 1.5V to 1.8V operating range. Consider the 42-contact TQFN package dimensions and thermal characteristics if heat dissipation is a critical factor in the PCB layout design.

Analog Switches - Special Purpose Part Context

This part belongs to the PI2PCIE series of differential multiplexer switches designed for high-speed serial interfaces. It is functionally related to other variants such as the PI2PCIE2412 and PI2PCIE2442, which share similar PCIe Gen II capabilities but may differ in pin configurations or additional features like bypass modes.

Analog Switches - Special Purpose Replacement Considerations

The PI2PCIE2412 serves as the base model without the specific packaging suffixes. Verify compatibility with the PI2PCIE2442 if a different pinout or exchange switch functionality is required. Always consult the latest datasheets to confirm pin-to-pin compatibility and electrical parameter equivalence before substituting.
