9DB102BGLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 9DB102BGLFT is a zero-delay buffer and jitter attenuator designed for PCI Express (PCIe) applications. It features a single differential input driving two differential HCSL outputs, operating at a maximum frequency of 101 MHz. The device integrates an internal Phase-Locked Loop (PLL) to provide low-jitter clock distribution. It functions within a supply voltage range of 3.135 V to 3.465 V and is housed in a 20-TSSOP package with a width of 4.40 mm. The component supports surface-mount installation and operates across a commercial temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• Zero-delay buffering architecture with integrated PLL for jitter attenuation
• 1:2 input-to-output ratio with differential HCSL outputs
• Maximum operating frequency of 101 MHz
• Supply voltage range of 3.135 V to 3.465 V

Application Specific Clock/Timing Applications

• PCI Express (PCIe) timing solutions
• Clock distribution networks requiring low jitter
• System-on-module clock generation

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'BGLFT' against current manufacturer documentation to confirm package type and RoHS compliance status. Check official Renesas channels for active production status, as availability may vary by region. Ensure the ordering information matches the required 20-TSSOP footprint and electrical specifications before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when a PCIe application requires a single differential source to drive two differential loads with minimal skew. The 101 MHz limit defines the maximum operational speed. Verify that the system power rail aligns with the 3.135 V to 3.465 V requirement and that the PCB layout accommodates the 20-TSSOP package dimensions.

Application Specific Clock/Timing Part Context

The 9DB102BGLFT belongs to the 9DB series of clock buffers from Renesas Electronics. This series is engineered specifically for high-performance digital interfaces like PCI Express. The part number indicates a 2-output configuration with HCSL outputs, distinguishing it from other variants in the family that may offer different output counts or logic families.

Application Specific Clock/Timing Replacement Considerations

Cross-reference with ICS9DB102BGLFT, which shares identical functional parameters and pinout compatibility. Confirm mechanical tolerance alignment between TSSOP-20 packages from IDT/Renesas sources before substitution.
