9DBL0843ANDGI8

Overview

The 9DBL0843ANDGI8 is a PCI Express zero-delay/fanout clock buffer manufactured by Renesas Electronics Corporation. It operates with a maximum frequency of 200MHz and features one input to eight outputs configuration. The device utilizes HCSL logic for both differential input and output signals. It is housed in a 48-VFQFPN (6x6) surface-mount package with exposed pad. The component supports a supply voltage range of 3.135V to 3.465V and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides zero-delay buffering and fanout distribution for PCIe clock signals
• Supports high-frequency operation up to 200MHz with low jitter performance
• Integrates HCSL compatible differential input and output interfaces

Applications

• PCI Express clock distribution networks
• High-speed digital system timing architectures
• Server and storage backplane designs

Procurement Notes

Verify the specific suffix 'GI8' against the official Renesas datasheet to confirm tape and reel packaging specifications and RoHS compliance status. Ensure the procurement source provides valid traceability documentation, as this component belongs to a specialized clock generation family requiring strict handling procedures during acquisition and storage.

Selection Notes

Select this component when designing systems requiring precise phase alignment between reference and distributed clocks. The zero-delay architecture minimizes propagation delay variations. Engineers must ensure the load capacitance on each of the eight outputs remains within the datasheet limits to maintain signal integrity at the specified 200MHz operating frequency.

Part Context

This part belongs to the 9DBL08x3 family of clock buffers designed specifically for PCI Express applications. It complements other variants like the 9DBL0841 series by offering different pinout or feature configurations while maintaining similar core timing performance characteristics for high-speed serial interface synchronization.
