9DBL0951BKILF

Overview

The 9DBL0951BKILF is a clock buffer from Renesas Electronics designed for PCIe Gen1, Gen2, and Gen3 applications. It features nine outputs with an impedance of 85 ohms, enabling direct connection to transmission lines without additional series resistors. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 200MHz. It utilizes HCSL output format and is housed in a 48-VFQFPN package measuring 6x6 mm. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports direct connection to 85-ohm transmission lines, eliminating the need for external series termination resistors
• Provides nine low-power HCSL outputs for high-speed data transfer timing
• Integrates PLL functionality for accurate clock distribution in PCIe systems

Applications

• PCI Express Gen1, Gen2, and Gen3 system designs
• High-speed data transfer timing distribution
• Server and storage infrastructure clock buffering

Procurement Notes

Verify the specific ordering suffix 'KILF' corresponds to the RoHS-compliant tape-and-reel packaging configuration as defined by Renesas. Confirm that the 48-VFQFPN (6x6) package dimensions match your PCB footprint requirements. Ensure the input frequency specifications align with your source clock before finalizing procurement orders.

Selection Notes

Select this component when designing PCIe interfaces requiring nine buffered outputs with 85-ohm impedance matching. It is suitable for applications needing direct transmission line connections to reduce bill-of-materials complexity. Consider its 200MHz operational limit and HCSL output characteristics against your system's speed and noise immunity requirements.

Part Context

This part belongs to the 9DBL series of clock buffers from Renesas Electronics. It is specifically engineered for PCI Express compliance, offering a compact solution for distributing reference clocks to multiple endpoints. The device simplifies board layout by integrating impedance-matched outputs directly into the package.
