Overview
The 9FGL6251AP202NDGI is an intelligent PCIe clock buffer and generator manufactured by Renesas Electronics, designed for single and dual-ported nVME SSDs. It supports Common (CC) and Independent Reference (IR) clocking architectures, making it suitable for U.2 and M.2 form factors. The device features two 100MHz Low-power HCSL outputs with 85Ω impedance and integrated terminations. It operates at 2.5V or 3.3V supply voltage with a typical power consumption of 65mW. The component is housed in a 4mm × 4mm 28-VQFP-N package.
Feature Summary
- Automatically detects input clock presence and switches modes
- Integrated crystal option available (Q option)
- Two 100MHz LP-HCSL outputs with 85Ω impedance
- SMBus-selectable -0.25% Spread Spectrum Clocking
Applications
- Single and dual-ported nVME SSDs
- PCIe master/slave applications
- Clock multiplexing systems
Procurement Notes
Verify the specific suffix NDGI against the manufacturer's datasheet to confirm the tray packaging configuration. Confirm RoHS compliance status directly from the official documentation before procurement. Ensure the ordering quantity aligns with the factory pack size requirements specified by Renesas Electronics.
Selection Notes
Select this model for designs requiring 85Ω output impedance with integrated terminations to reduce external resistor count. Choose the Q variant if an internal crystal option is preferred over an external one. Verify that the system architecture supports either SRnS/IR or CC configurations as defined by the 202 suffix.
Part Context
This part belongs to the 9FGL6251 series, which serves as the root component for the 31, 41, and 51 variants. The series is optimized for PCIe Gen 1–6 compliance and includes intelligent features for clock mode switching and reference output generation.
Replacement Considerations
Consult the official datasheet for confirmed substitute part numbers within the 9FGL6251 family. Verify pin compatibility and electrical parameters before substituting with other clock generator models.
