9DB102BFLF

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 9DB102BFLF is a PCI Express (PCIe) zero-delay buffer and jitter attenuator integrated circuit. It features a single input to two differential outputs configuration, operating with a maximum frequency of 101 MHz. The device functions within a supply voltage range of 3.135 V to 3.465 V and is housed in a 20-SSOP package with a width of 3.90 mm. Designed for surface mount installation, it supports an industrial operating temperature range from 0°C to 70°C. This component integrates a Phase-Locked Loop (PLL) to manage clock signal integrity.

Application Specific Clock/Timing Feature Summary

• PCI Express Zero-Delay Buffer: Provides low-jitter clock distribution specifically optimized for PCIe applications.
• Jitter Attenuation: Incorporates PLL technology to reduce input clock phase noise and timing errors.
• Differential I/O: Features one differential input and two differential outputs for robust signal transmission.
• Standard Packaging: Supplied in a 20-pin Shrink Small Outline Package (SSOP).

Application Specific Clock/Timing Applications

• PCI Express (PCIe) system clock generation and distribution.
• High-speed digital interface timing synchronization.
• Server and storage controller board clocking.

Application Specific Clock/Timing Procurement Notes

The 9DB102BFLF is listed as an obsolete or end-of-life product by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. Buyers should confirm the specific suffix 'BFLF' matches their design requirements, as packaging or material specifications may differ from active equivalents. Cross-referencing with the official datasheet is recommended before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when designing for PCIe Gen1/Gen2 interfaces requiring a 1:2 fan-out with jitter attenuation capabilities up to 101 MHz. Ensure the PCB layout accommodates the 20-SSOP footprint (3.90mm width). Verify that the power supply rails strictly adhere to the 3.135V–3.465V specification to maintain proper PLL operation and output swing characteristics.

Application Specific Clock/Timing Part Context

This part belongs to the 9DB102 series of clock buffers. Variants such as the 9DB102BGLFT offer similar electrical performance but utilize a TSSOP-20 package instead of SSOP. The 'FLF' suffix typically denotes the specific package type and lead-free compliance status defined by Renesas for this particular form factor.

Application Specific Clock/Timing Replacement Considerations

The 9DB102BGLFT is a pin-compatible alternative within the same family, differing primarily in the TSSOP-20 package versus the SSOP-20 package of the 9DB102BFLF. Designers must verify mechanical fitment if substituting packages. Other members of the 9DB102 series may share functional similarities but require careful review of pinouts and thermal characteristics.
