PI2PCIE2412ZHEX

Analog Switches - Special Purpose Overview

The PI2PCIE2412ZHEX is a 1.8V, PCI Express Gen2 compliant multiplexer/demultiplexer switch manufactured by Diodes Incorporated under the Pericom brand. 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%. Key electrical parameters include a maximum bit-to-bit skew of 7 ps, channel-to-channel skew of 35 ps, and -23 dB crosstalk at 3 GHz. It utilizes a 42-contact TQFN (ZH42) package.

Analog Switches - Special Purpose Feature Summary

• Supports PCI Express Gen2 performance with low signal attenuation through minimized impedance design.
• Provides low bit-to-bit skew and minimal channel-to-channel crosstalk for signal integrity.
• Features high ESD tolerance on I/O pins and select control lines.

Analog Switches - Special Purpose Applications

• Routing of PCI-Express Gen2 signals with low signal attenuation
• Multiplexing differential data streams in high-speed interface systems

Analog Switches - Special Purpose Procurement Notes

Verify the component authenticity against official Diodes Incorporated documentation. Confirm that the ZH42 package matches the required PCB footprint. Ensure the operating environment stays within the specified temperature range of -40°C to +85°C. Check that the power supply voltage remains strictly between 1.5V and 1.8V to maintain compliance with PCI Express specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring the switching of two PCIe Gen2 lanes. Ensure the system supports the specific 1.5V to 1.8V supply voltage requirements. Verify that the 42-contact TQFN package fits the available board space. Consider the 7 ps bit-to-bit skew limit if strict timing alignment is critical for the application.

Analog Switches - Special Purpose Part Context

This part belongs to the PI2PCIE series of high-performance multiplexer switches designed specifically for PCI Express applications. It is produced by Pericom Semiconductor Corporation, which is now part of Diodes Incorporated. The series focuses on maintaining signal integrity in high-speed digital interfaces.

Analog Switches - Special Purpose Replacement Considerations

Check for direct substitutes within the PI2PCIE family or other PCIe switch ICs from Diodes Incorporated. Ensure any replacement maintains the 42-contact TQFN package and 1.8V operation. Verify that the substitute meets the same 5.0 Gbps speed and skew specifications.
