ZL40241LDG1

Overview

The ZL40241LDG1 is a clock buffer manufactured by Microchip Technology, housed in a VQFN-32 package. It functions as a ten-output LVCMOS fanout buffer designed for low skew and low additive jitter applications. The device supports multiple input types including CML, HCSL, LVCMOS, LVDS, LVPECL, and SSTL, with a maximum input frequency of 200 MHz. It operates within a supply voltage range of 1.35 V to 3.465 V and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Ten LVCMOS outputs providing high fanout capability
• Supports diverse input standards: CML, HCSL, LVCMOS, LVDS, LVPECL, SSTL
• Maximum operating frequency of 200 MHz
• Wide supply voltage range from 1.35 V to 3.465 V

Applications

• Fanout buffering for FPGA and ASIC clock networks
• Telecommunications equipment requiring low jitter clocking
• Industrial control systems with mixed-signal interfaces

Procurement Notes

Verify the specific suffix 'LDG1' against the official Microchip datasheet to confirm pinout, packaging dimensions, and electrical characteristics. Ensure compatibility with the target PCB footprint for the VQFN-32 package. Confirm RoHS compliance status through the manufacturer's current documentation before procurement.

Selection Notes

Select this component when a single differential or single-ended clock source needs to drive ten LVCMOS loads. It is suitable for designs requiring support for various input logic levels such as LVDS or LVPECL. Consider thermal performance and board space constraints associated with the VQFN-32 package during layout planning.

Part Context

The ZL40241 belongs to the ZL402x family of clock buffers from Microchip Technology. This family offers various fanout configurations with options for LVPECL or LVDS outputs. These devices are engineered to provide low offset and ultra-low additive jitter, often used in conjunction with miClockSynth synthesizers for complete clock tree solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the ZL402x series that may offer different output counts or voltage ranges. Verify if alternative packages like QFN variants are available from Microchip for the same functional specification.
