ZL40240LDF1

Overview

The ZL40240LDF1 is a clock fanout buffer manufactured by Microchip Technology, designed for high-frequency signal distribution. It operates with a maximum frequency of 750 MHz and supports a 1:8 input-to-output ratio. The device features differential inputs and outputs, accepting CML, HCSL, LVCMOS, LVDS, and LVPECL signals. Power supply voltage ranges from 2.375 V to 3.465 V. It is housed in a 32-VFQFN package with exposed pad, suitable for surface mount applications across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports 1:8 fanout configuration with differential input/output
• Maximum operating frequency of 750 MHz
• Compatible with multiple input logic levels including CML, HCSL, LVCMOS, LVDS, and LVPECL
• Operates on a single supply voltage between 2.375 V and 3.465 V

Applications

• High-speed data communication systems requiring clock distribution
• Server and storage infrastructure timing networks
• Telecommunications equipment clock synchronization

Part Context

The ZL40240LDF1 belongs to the ZL402x series of clock fanout buffers from Microchip. This series provides low skew and ultra-low added jitter performance. The ZL40240 variant specifically offers a 1:8 split ratio, distinguishing it from other models like the ZL40218 or ZL40219 which may have different output counts or frequency capabilities within the same family.

Replacement Considerations

The ZL40218LDG1 is listed as a parameter-equivalent alternative. Both devices share similar specifications regarding fanout ratio and frequency limits. Verification of pin compatibility and specific electrical characteristics against the original design requirements is recommended before substitution.
