ZL40235LDF1

Overview

The ZL40235LDF1 is a clock buffer manufactured by Microchip Technology, belonging to the miSmartBuffer series. It functions as a fanout buffer with two inputs and five outputs, supporting LVPECL, LVDS, and HCSL signal standards. The device is housed in a surface-mount package and operates within a supply voltage range of 1.71 V to 3.465 V. Designed for high-frequency applications, it delivers low skew and ultra-low added jitter characteristics essential for precise timing distribution.

Feature Summary

• Dual-input, five-output fanout buffer architecture
• Supports LVPECL, LVDS, and HCSL output formats
• miSmartBuffer series technology for low skew and jitter
• Operates on 1.71 V to 3.465 V power supply

Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure utilizing LVDS or LVPECL interfaces
• Server and storage backplanes needing HCSL compatibility
• Test equipment requiring low-jitter clock buffering

Procurement Notes

The ZL40235LDF1 is supplied in a reel packaging format. Verification of the manufacturing source confirms Microchip Technology as the producer. Buyers should confirm the specific suffix requirements for tape-and-reel quantities against official distributor listings to ensure correct ordering specifications.

Selection Notes

Select the ZL40235LDF1 when a dual-input configuration driving five differential or single-ended loads is required. Ensure the system design accommodates the 1.71 V to 3.465 V operating voltage. Verify that the target interface standards (LVPECL, LVDS, or HCSL) align with the buffer's supported output types for proper impedance matching.

Part Context

This component is part of the broader ZL402x family of clock buffers from Microchip. The family includes variants with different input/output ratios and output standards. The ZL40235 specifically addresses designs requiring five buffered outputs from two sources, distinguishing it from other models like the ZL40221 or ZL40251 which offer different channel counts.

Replacement Considerations

Direct replacements within the same family include the ZL40235LDG1, which differs primarily in packaging type (tray versus reel). Other ZL402x series devices may serve as functional alternatives if the input/output ratio and voltage requirements are compatible.
