9DB801CGLF

Overview

The Renesas 9DB801CGLF is a PCI Express (PCIe) zero-delay buffer integrated circuit designed for high-speed clock distribution. It features an input-to-output ratio of 1:8, supporting differential HCSL inputs and differential LVDS outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 400MHz. Packaged in a 48-TSSOP surface-mount format, it functions within an industrial temperature range of 0°C to 70°C. This component is engineered to maintain signal integrity in PCIe Gen1 applications by eliminating propagation delay skew between the single input and eight buffered outputs.

Feature Summary

• Zero-delay buffering architecture ensuring minimal skew between input and output clocks
• Supports 1:8 fan-out with differential HCSL input and differential LVDS outputs
• Operates at frequencies up to 400MHz with a 3.135V to 3.465V supply voltage
• Available in a 48-TSSOP surface-mount package

Applications

• PCI Express Gen1 clock distribution networks
• High-speed data acquisition systems requiring precise clock synchronization
• Telecommunications equipment utilizing PCIe interfaces

Procurement Notes

The 9DB801CGLF is listed as a discontinued product by Renesas Electronics Corporation. Verification of availability should focus on surplus distributors or existing stock rather than direct manufacturing orders. Buyers must confirm the specific suffix 'C' denotes the TSSOP-48 package variant and verify RoHS compliance status through current datasheets, as end-of-life notices may affect long-term sourcing reliability.

Selection Notes

Select the 9DB801CGLF when designing PCIe Gen1 systems requiring a single source clock to drive eight downstream components with strict timing alignment. Ensure the design accommodates the 3.135V to 3.465V power rail requirements. Verify that the target PCB layout supports the 48-TSSOP footprint. For higher generation PCIe standards or different I/O voltage levels, alternative models such as the 9DB803 series should be evaluated.
