9DBL0841BKILFT

Overview

The 9DBL0841BKILFT is a zero-delay buffer integrated circuit manufactured by Renesas Electronics Corporation, designed for PCI Express (PCIe) clock distribution. It features a single input to eight output configuration with differential HCSL signaling on both input and output sides. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 200MHz. It incorporates an internal Phase-Locked Loop (PLL) and functions across an industrial temperature range of -40°C to 85°C. The component is housed in a 48-VFQFN package with a bare pad, measuring 6x6mm.

Feature Summary

• Zero-delay buffering architecture for PCIe applications
• 1:8 input-to-output ratio with differential HCSL signaling
• Internal PLL for clock generation and distribution
• Operates at frequencies up to 200MHz

Applications

• PCI Express Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

This component has been officially declared obsolete and is no longer in manufacturing. Verification of availability should focus on replacement parts rather than original stock. Buyers must confirm the specific suffix differences between the discontinued part and its substitutes to ensure pinout and electrical compatibility matches the design requirements.

Selection Notes

Designers requiring this functionality should evaluate the 9DBL0841CKILFT as the primary recommended substitute from Renesas. Selection criteria must account for the identical 48-VFQFN footprint and 1:8 differential HCSL configuration. Verify that the replacement part meets the same 200MHz frequency and 3.3V supply specifications required by the target PCIe application.

Part Context

The 9DBL0841 series belongs to Renesas' specialized line of low-power PCIe clock buffers and generators. These components are engineered to provide precise clock distribution with minimal jitter for high-speed serial interfaces. The 9DBL0841 variant specifically addresses the need for multiple clock outputs derived from a single source in complex motherboard or accelerator designs.

Replacement Considerations

The 9DBL0841CKILFT is listed as a manufacturer-recommended alternative. Ensure the 'C' suffix variant maintains the necessary electrical parameters and physical dimensions for direct board-level substitution.
