PI3EQX10908ZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX10908 is an eight-channel PCIe ReDriver designed for high-performance signal integrity. It supports serial link rates up to 11.3Gbps and KR backplane applications. The device provides per-channel programmable equalization, output swing, de-emphasis, and amplifier gain to mitigate inter-symbol interference. Key electrical parameters include a supply voltage of 3.3V±10%, transmit VOD up to 1200 mVp-p, transmit de-emphasis up to 9 dB, and receive equalization up to 35.7 dB. It features a flow-through pinout in a 54-contact TQFN package (11mm x 5mm).

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports data rates up to 11.3Gbps with independent channel configuration for receiver equalization, output swing, de-emphasis, and amplifier gain.
• Enables extended transmission over lossy copper cables or backplanes by opening completely closed input eyes caused by inter-symbol interference.
• Offers flexible programming via pin straps, I2C master/slave control, or external EEPROM loading without requiring an external microprocessor.

Signal Buffers, Repeaters, Splitters Applications

• 10Gb and 40Gb Ethernet systems
• 10Gb fiber channel networks
• 10Gb SFI, XFI, and KR interfaces

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and tape/reel specifications. Ensure compatibility with system power requirements and interface protocols before integration. Confirm RoHS compliance status through official datasheets.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending signal paths over long copper traces or connectors is required. Evaluate channel count needs against the eight-differential channel architecture. Consider I2C versus pinstrap configuration methods based on system design flexibility and manufacturing constraints.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the Pericom PI3EQX series of PCIe Redrivers. It shares functional similarities with other models like the PI3EQX32908 but operates at lower data rates suitable for 10Gbps standards. The family focuses on signal restoration for high-speed serial links.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Check for direct substitutes within the PI3EQX series that match the 54-contact TQFN footprint. Verify pinout compatibility if replacing with variants offering different channel counts or data rate capabilities.

Signal Buffers, Repeaters, Splitters FAQ

How is the device programmed?

Configuration can be applied via pin straps, software using I2C master/slave control, or automatically loaded from an external EEPROM upon power-up.

What is the maximum receive equalization capability?

The receiver supports up to 35.7 dB of equalization to compensate for signal loss in the interconnect medium.

Does the device support automatic configuration?

Yes, in EEPROM mode, configuration information is automatically loaded on power-up, eliminating the need for an external microprocessor or software driver.
