PI7C9X2G404SLBQFDE

Overview

The PI7C9X2G404SLBQFDE is an automotive-grade PCI Express 2.1 packet switch from Diodes Incorporated, featuring four ports and four lanes. It operates within a temperature range of -40°C to +85°C and complies with AEC-Q100 Grade 3 standards. The device supports one x1 or x2 upstream port and three x1 downstream ports, providing flexible expansion for various application-specific ICs. Typical power dissipation is 650 mW in L0 mode and 200 mW in L1 mode. It utilizes a 128-pin LQFP package measuring 14mm x 14mm.

Feature Summary

• Supports Data Poisoning, End-to-End CRC, Advanced Error Reporting, and IEEE 1149.1 JTAG interface.
• Enables Link Power Management across L0, L0s, L1, L2, L2/L3Ready, and L3 states with active state power management.
• Features programmable driver current and de-emphasis levels at each individual port.
• Provides up to 512-byte maximum payload size support.

Applications

• Automotive Telematics and Infotainment
• In-vehicle Wireless AP/Router
• V2V System
• ADAS
• Vehicle Navigation

Procurement Notes

Verify the specific suffix 'QFDEX' against official documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with AEC-Q100 Grade 3 requirements for your target automotive environment. Cross-reference the part number with the manufacturer's latest datasheet to validate pinout and electrical specifications before finalizing procurement.

Selection Notes

Select this component when designing systems requiring four PCIe lanes with strict automotive reliability standards. Consider the 128-pin LQFP package dimensions for PCB layout constraints. Evaluate power consumption profiles in L0 and L1 modes to ensure thermal management aligns with system capabilities. Confirm that the integrated clock buffer meets the timing requirements of connected endpoints.

Part Context

This part belongs to the PI7C9X2G404xxQ family of automotive-compliant PCIe switches. It shares core functionality with variants like the PI7C9X2G404ELQ but differs in package type and specific ordering suffixes. The family is designed to provide high-performance switching solutions for demanding automotive applications while maintaining low power consumption.

Replacement Considerations

PI7C9X2G404SLQ serves as a non-tape-and-reel variant within the same family. Verify package compatibility and suffix differences before substitution. Consult official documentation for any functional distinctions between reel and tray packaging options.
