PI7C9X2G304EVAQ2ZXAEX

Specialized Overview

The PI7C9X2G304EVAQ2ZXAEX is an automotive-compliant PCI Express 2.1 packet switch featuring three ports and four lanes. It includes one x1 or x2 upstream port and two x1 downstream ports, housed in a 136-pin aQFN package measuring 10mm by 10mm. The device operates within a temperature range of -40°C to +105°C and meets AEC-Q100 Grade 2 standards. Typical latency is under 150ns, with power dissipation at 300mW in L0 mode and 35mW in L1.1 D3hot sub-state.

Specialized Feature Summary

• Supports cut-through and store-and-forward switching modes
• Integrated 100MHz clock buffer for each downstream port
• Advanced error reporting, logging, and data poisoning support
• Configurable driver current and de-emphasis levels per port

Specialized Applications

• Automotive telematics and infotainment platforms
• In-vehicle wireless access points and routers
• Vehicle-to-everything (V2V) systems
• Advanced Driver Assistance Systems (ADAS)
• Vehicle navigation and safety/security modules

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The 'X' suffix indicates tape and reel packaging. Confirm that the component meets all required automotive quality standards and environmental compliance specifications before integration into production designs.

Specialized Selection Notes

Select this component for applications requiring automotive-grade reliability and low power consumption. Ensure the design supports the necessary voltage levels and utilizes the integrated clock buffers. Verify compatibility with the target system's PCIe endpoint requirements and evaluate the thermal performance within the specified operating temperature range.

Specialized Part Context

This part belongs to the PI7C9X2G304/404EVQ family, designed specifically for automotive environments. It complements other switches in the series by offering a compact solution for expanding PCIe connectivity from MCUs or FPGAs to multiple endpoints while maintaining strict automotive qualification standards.

Specialized Replacement Considerations

The PI7C9X2G404EVAQ2ZXAEX serves as a functional alternative within the same family, providing four downstream ports instead of three. Both devices share identical packages, electrical characteristics, and automotive qualifications, allowing for direct pin-compatible substitution where additional port density is required.
