ZL40231LDF1

Overview

The ZL40231LDF1 is a low skew, low additive jitter clock driver manufactured by Microchip Technology. It operates within an industrial temperature range of -40°C to 85°C and utilizes a 48-VFQFN package with exposed pad dimensions of 7 mm x 7 mm. The device features a single circuit with differential input and output capabilities, supporting LVCMOS outputs that also operate at 3.3 V supply. Key electrical characteristics include a maximum load capacitance of 1 pF and a differential mux for input regulation. This component is classified under logic integrated circuits designed for low skew clock driving applications.

Feature Summary

• Low skew and low additive jitter performance
• LVCMOS output capability operating at 3.3 V supply
• Differential input multiplexer (DIFFERENTIAL MUX) for input regulation
• Maximum load capacitance of 1 pF

Applications

• Low skew clock distribution networks
• Systems requiring ultra-low additive jitter clock drivers
• Industrial equipment timing circuits

Procurement Notes

Verify the specific suffix 'LDF1' against the official Microchip datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the 48-VFQN footprint and check moisture sensitivity levels prior to assembly. Confirm that the 3.3 V LVCMOS output requirement aligns with the target system voltage domains.

Selection Notes

Select this component when low skew and minimal additive jitter are critical for signal integrity. Verify that the 1 pF load capacitance specification meets the downstream receiver requirements. Ensure the design supports the differential input configuration and that the 48-pin QFN package fits the PCB layout constraints.

Part Context

The ZL40231 belongs to the broader family of Microchip clock buffer and driver solutions. It is distinct from other models like the ZL40264 or ZL40235 by its specific focus on low skew performance and LVCMOS output options. It serves as a specialized driver within the company's portfolio for high-speed digital systems requiring precise timing control.

Replacement Considerations

Cross-reference with other Microchip low skew clock drivers such as the ZL40231LDG1 for tray packaging alternatives. Verify pinout compatibility if substituting with similar devices from the same manufacturer.
