PI7C9X3G606GPQ3FCAEX

Overview

The PI7C9X3G606GPQ3FCAEX is an automotive-grade PCI Express 3.0 packet switch manufactured by Diodes Incorporated. It features six ports and six lanes, operating within a temperature range of -40°C to +85°C. The device supports up to 512-byte maximum payload sizes and delivers typical forwarding latency under 150ns. It utilizes two power rails at 0.95V and 1.8V, consuming approximately 2.5W. The component is housed in a 144-pin FC LFBGA package (FCA144) with dimensions of 10mm x 10mm.

Feature Summary

• Supports elastic bifurcation for upstream and downstream ports to accommodate flexible system topologies.
• Integrates adaptive equalization including a 5-tap Decision Feedback Equalizer and 3-tap TX feed forward equalizer.
• Provides advanced Reliability, Availability, and Serviceability through end-to-end data protection and error handling mechanisms.
• Enables multi-host applications with support for up to three Cross-Domain End-Point ports.

Applications

• Automotive Zonal Central Controllers
• Advanced Driver Assistance Systems (ADAS)
• In-vehicle Telematics units
• Infotainment systems
• Cockpit Control modules

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and compliance details. Confirm that the AEC-Q100 Grade 3 qualification aligns with your project's automotive reliability standards. Ensure design compatibility with the specified 144-pin FCA package and moisture sensitivity level prior to procurement.

Selection Notes

Select this component when a six-lane PCIe 3.0 solution is required for automotive environments. Consider alternative family members like the PI7C9X3G816GPQ if higher lane counts or different port configurations are necessary. Evaluate the thermal performance and power consumption characteristics relative to the specific application constraints.

Part Context
