9DB306BLLF

Overview

The 9DB306BLLF is a high-performance, lead-free (RoHS 6 compliant) 1-to-6 Differential-to-LVPECL Jitter Attenuator designed for PCI Express systems. It features one differential clock input supporting LVPECL, LVDS, LVHSTL, SSTL, and HCSL types. The device operates on a 3.3V supply with an input frequency range of 90MHz to 140MHz and a VCO range of 450MHz to 700MHz. Maximum output frequency is 140MHz. Key timing specifications include a maximum output skew of 135ps, cycle-to-cycle jitter of 30ps, and typical RMS phase jitter of 3ps at 100MHz (1.5MHz - 22MHz). It functions within a commercial ambient temperature range of 0°C to 70°C.

Feature Summary

• Six differential LVPECL output pairs
• Supports multiple input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Two PLL bandwidth modes: Low (~500kHz) and High (1MHz)
• Lead-free (RoHS 6) package

Applications

• PCI Express systems in desktop PCs
• Attenuating jitter from low bandwidth, high phase noise PLL synthesizers
• Zero delay buffering for system boards

Procurement Notes

Verify the specific suffix 'BLLF' against official Renesas documentation to confirm package type and moisture sensitivity level. Ensure the component meets RoHS 6 compliance requirements for your assembly process. Check current product status as this model may be obsolete or discontinued.

Selection Notes

Select this component when PCI Express applications require attenuation of high-frequency random and deterministic jitter from reference clocks. Choose the low bandwidth mode for significant jitter attenuation while passing triangular spread spectrum profiles, or high bandwidth mode for greater spread spectrum modulation support. Verify that the 140MHz maximum output frequency aligns with system requirements.

Part Context

The 9DB306 series addresses jitter issues in PCI Express architectures where standard PLL synthesizers introduce excessive noise. This specific part provides a zero-delay buffer solution to clean up clock signals before distribution to SerDes components, ensuring signal integrity in high-speed digital interfaces.
