9DB633AFLF

Overview

The 9DB633AFLF is a clock buffer and distribution IC from Renesas Electronics, designed for PCI Express (PCIe) applications. It features a single circuit with one input and six outputs, operating within a supply voltage range of 3.135 V to 3.465 V. The device supports a maximum frequency of 110 MHz and utilizes HCSL output signaling. Packaged in a 28-TSSOP format, it operates reliably across temperatures from 0°C to +70°C. This component functions as a zero-delay buffer to distribute clock signals efficiently in high-speed digital systems.

Feature Summary

• Six-output PCIe fan-out buffer configuration
• HCSL output signaling for low noise performance
• Operates at frequencies up to 110 MHz
• Integrated PLL for clock synchronization

Applications

• PCI Express system clock distribution
• High-speed data acquisition systems
• Telecommunications equipment timing networks

Procurement Notes

Verify the specific suffix 'AFLF' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure that the 28-TSSOP footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-ended or differential input requires expansion into six matched HCSL outputs. Confirm that the 3.3V nominal supply voltage aligns with the system power architecture and that the 0°C to +70°C industrial temperature range meets environmental specifications.

Part Context

This part belongs to the 9DB633 family of PCIe clock buffers. It serves as a signal integrity solution for distributing reference clocks to multiple PCIe endpoints or controllers, ensuring minimal skew between output channels in complex motherboard designs.

Replacement Considerations

The 9DB633AGLFT is a verified alternative offering identical electrical characteristics but housed in a 28-TSSOP package with different lead form or labeling variations. Verify pin-to-pin compatibility before substitution.
