9DB102BFLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 9DB102BFLFT is a PCI Express (PCIe) zero-delay buffer and jitter attenuator IC. It features a single PLL-based circuit with a 1:2 input-to-output ratio, supporting differential inputs and outputs. The device operates at a maximum frequency of 101 MHz and requires a supply voltage between 3.135 V and 3.465 V. Designed for surface-mount installation, it is housed in a 20-SSOP package with a width of 3.90 mm. The component is rated for an operating temperature range of 0°C to 70°C and is currently marked as obsolete by the manufacturer.

Application Specific Clock/Timing Feature Summary

• PCIe Zero-Delay Buffer: Integrates a PLL for jitter attenuation within PCIe timing solutions.
• Signal Conversion: Converts differential clock inputs to HCSL differential outputs.
• Frequency Capability: Supports maximum input frequencies up to 101 MHz.
• Package Configuration: Delivers signals via a 20-SSOP (0.154"/3.90mm wide) surface-mount housing.

Application Specific Clock/Timing Applications

• PCI Express (PCIe) system clock distribution
• Jitter attenuation for high-speed digital interfaces
• Clock buffering in server and storage architectures

Application Specific Clock/Timing Procurement Notes

This component is officially listed as obsolete or end-of-life by Renesas Electronics. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative sourcing may involve third-party inventory or approved replacement parts from the same product family. Compliance with RoHS3 standards is confirmed for this part number.

Application Specific Clock/Timing Selection Notes

Select the 9DB102BFLFT when a 1:2 split ratio with jitter cleaning is required for PCIe applications. Ensure the design accommodates the 20-SSOP footprint and the specific 3.135V to 3.465V power rail constraints. For designs requiring wider commercial temperature ranges (-40°C to 85°C), consider the 9DB102BGILFT variant instead.

Application Specific Clock/Timing Part Context

The 9DB102BFLFT belongs to the 9DB102 series of zero-delay buffers. It shares core functionality with the 9DB102BGLFT but differs in packaging (SSOP vs. TSSOP) and thermal rating (Commercial vs. Extended). This specific suffix indicates the standard commercial grade version intended for general-purpose industrial electronics.

Application Specific Clock/Timing Replacement Considerations

Public documentation lists the 9ZXL0451EKILFT as a manufacturer-recommended replacement for similar 1:4 configurations, though pinout compatibility must be verified. The 9DB102BGILFT serves as a direct functional alternative with extended temperature ratings and a TSSOP package.
