ZL40235LDG1

Overview

The ZL40235LDG1 is a clock buffer from the miSmartBuffer series manufactured by Microchip Technology. It functions as a dual fanout buffer supporting LVPECL, LVDS, and HCSL output formats. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports maximum frequencies up to 1.035 GHz. Designed for low skew and low additive jitter applications, it utilizes a QFN package suitable for surface mount technology. The component is rated for industrial temperature ranges spanning from -40°C to +85°C.

Feature Summary

• Dual fanout buffer architecture with independent output enable controls
• Supports multiple output standards including LVPECL, LVDS, and HCSL
• Maximum operating frequency of 1.035 GHz
• Low skew and low additive jitter performance characteristics

Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure utilizing differential signaling
• Server and storage backplanes needing multi-standard clock buffering

Procurement Notes

Verify the specific suffix 'LDG1' against official Microchip documentation to confirm package type and moisture sensitivity level. Ensure ordering quantities align with factory packaging constraints if applicable. Confirm RoHS compliance status through current datasheets prior to procurement.

Selection Notes

Select this component when dual-channel buffering with mixed standard support (LVPECL/LVDS/HCSL) is required. Compare propagation delay specifications against system timing budgets. Verify that the QFN-56 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the ZL40235 family of miSmartBuffer devices. It shares functional similarities with other members like the ZL40235LDF1 but differs in packaging configuration. The LDG1 suffix typically denotes a tray-packaged QFN variant compared to reel-based alternatives.

Replacement Considerations

Direct substitutes include other ZL40235 variants such as ZL40235LDF1, provided package differences are accommodated. Cross-reference pinouts and electrical parameters with Microchip's compatibility matrix before substitution.
