PI3PCIE3415AZHEX

Specialized Overview

The PI3PCIE3415AZHEX is a 3.3V, PCI Express 3.0 compliant multiplexer/demultiplexer switch manufactured by Diodes Incorporated. It provides four differential channels configured as two 2:1 switches, supporting data rates up to 8.0 Gbps per lane. The device operates within a supply voltage range of 3.0V to 3.6V and an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum bit-to-bit skew of 10ps, channel-to-channel skew of 20ps, and a -3dB bandwidth of 8.4 GHz. It features low insertion loss of -1.2dB at 4GHz and high off-isolation of -22dB at 4GHz.

Specialized Feature Summary

• Supports bi-directional operation for routing full PCI Express 3.0 lanes between two locations.
• Optimized pinout layout designed for placement directly between two PCIe slots.
• Minimizes impedance and signal attenuation through unique design techniques.
• Provides low crosstalk and low channel-to-channel skew to meet PCI Express specifications.

Specialized Applications

• Routing of PCI Express 3.0 signals
• DisplayPort 1.2 signal routing
• USB 3.0 signal switching
• SAS 2.0 and SATA 3.0 interface management

Specialized Procurement Notes

Verify the component against the official datasheet DS40126 Rev 1-2 to confirm authenticity. Ensure the ordering suffix matches the required package type, such as ZH for the 42-contact TQFN or ZL for the 40-contact variant. Confirm that the specific part number aligns with the intended application requirements before finalizing procurement.

Specialized Selection Notes

Select this component when designing systems requiring low-loss switching for high-speed serial interfaces like PCIe 3.0. Consider the 42-contact TQFN package for standard layouts or the 40-contact version if space constraints require a smaller footprint. Verify that the 3.3V operating voltage and industrial temperature range suit the target environment.

Specialized Part Context

This device belongs to the PI3PCIE3415A product line from Diodes Incorporated, specifically engineered for high-performance signal routing. It is part of a broader family of PCIe interface ICs designed to manage signal integrity in complex motherboard and server architectures where multiple high-speed lanes must be selectively routed.

Specialized Replacement Considerations

Check for updated revisions of the PI3PCIE3415A series. Verify compatibility with alternative mux/demux ICs from other manufacturers only if they match the exact pinout, voltage, and performance specifications documented in the official datasheet.

Specialized FAQ

What is the maximum data rate supported by the PI3PCIE3415AZHEX?

The device supports PCI Express 3.0 performance with a data rate of up to 8.0 Gbps per lane.

How does the SEL pin control the switching function?

The SEL pin controls the mux through a flow-through latch. A logic low routes inputs to output 'a', while a logic high routes inputs to output 'b'.

What is the typical bit-to-bit skew specification?

The maximum bit-to-bit skew within the same differential pair is specified as 10 ps.
