9DBL0455PGGI

Overview

The 9DBL0455PGGI is a 4-output PCIe clock fanout buffer supporting Gen1 through Gen7. It operates on a 3.3V supply with LP-HCSL outputs and accepts HCSL inputs. The device features additive phase jitter of 300fs RMS typical, supports spread spectrum inputs, and includes SMBus configuration. It is housed in a 20-TSSOP package.

Feature Summary

• Supports PCIe Gen1 through Gen7 applications
• Provides four low-power HCSL differential outputs
• Accepts spread spectrum input signals
• Configurable via dedicated pins or SMBus interface

Applications

• PCIe Gen1 clock distribution
• PCIe Gen2 clock distribution
• PCIe Gen3 clock distribution
• PCIe Gen4 clock distribution
• PCIe Gen5 clock distribution

Procurement Notes

Verify the specific suffix PGGI against official Renesas documentation to confirm pin compatibility and package type. Ensure the procurement channel provides valid RoHS compliance data. Confirm that the active status aligns with current production schedules. Request detailed datasheets for accurate electrical parameter validation before integration into design specifications.

Selection Notes

Select this component when designing systems requiring PCIe Gen1 through Gen7 clock buffering. It is suitable for architectures needing four differential outputs from a single source. Consider its 3.3V operation and LP-HCSL output signaling for compatibility with standard PCIe receiver inputs. Evaluate SMBus configuration needs if dynamic adjustment is required.

Part Context

This part belongs to the 9DBL04xx family of PCIe clock buffers from Renesas. It complements other variants like the 9DBL0452 by offering specific output configurations and packaging options. The family targets high-speed serial link applications requiring precise timing and low jitter performance across multiple PCIe generations.

Replacement Considerations

Check the 9DBL0452 datasheet for potential functional overlap. Verify pin-to-pin compatibility and electrical parameters before substitution. Ensure the alternative part supports the same PCIe generation requirements and output signaling standards.
