9DB102BGLF

Application Specific Clock/Timing Overview

The Renesas 9DB102BGLF is a PCI Express (PCIe) zero-delay buffer and jitter attenuator designed for high-speed digital interfaces. It features a single differential input and two differential outputs, operating within a supply voltage range of 3.135V to 3.465V. The device supports maximum frequencies up to 101MHz and utilizes an internal Phase-Locked Loop (PLL) for clock conditioning. Housed in a 20-TSSOP package with a width of 4.40mm, it operates within a commercial temperature range of 0°C to 70°C. The output signaling format is High-Current Switched Logic (HCSL), ensuring compatibility with PCIe reference clock architectures.

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'BGLF' against current manufacturer documentation to confirm package type and RoHS compliance status. Check for active production status or obsolescence notices, as component availability may vary by region. Ensure the required operating temperature range aligns with the commercial grade specification (0°C to 70°C). Cross-reference datasheet revision dates to confirm electrical parameters match design requirements.

Application Specific Clock/Timing Selection Notes

Select this component when a single-input, dual-output PCIe clock buffer with integrated jitter attenuation is required. Verify that the system power supply falls within the 3.135V to 3.465V range. Confirm that the HCSL output logic levels are compatible with downstream receiver inputs. Consider the 20-TSSOP footprint constraints during PCB layout. Compare against other members of the 9DB102 family if different pin counts or temperature ranges are needed.

Application Specific Clock/Timing Part Context

The 9DB102BGLF belongs to the Renesas 9DB102 series of PCIe clock buffers. This series is engineered specifically for meeting the stringent jitter specifications defined by the PCI-SIG standards. It serves as a critical timing element in systems requiring clean, stable reference clocks for PCIe lanes. The 'BGLF' designation typically indicates the TSSOP package variant and lead-free construction.

Application Specific Clock/Timing Replacement Considerations

Direct replacements within the same family include the 9DB102BFLFT (SSOP package) and 9DB102BGILFT (TSSOP package, industrial temp). Verify pinout compatibility and thermal characteristics before substituting. Consult the official Renesas cross-reference guide for qualified alternate part numbers.
