ZL40241LDF1

Overview

The ZL40241LDF1 is a ten-output LVCMOS fanout buffer manufactured by Microchip Technology. It operates with input frequencies up to 200 MHz and supports multiple input types including CML, HCSL, LVCMOS, LVDS, LVPECL, and SSTL. The device functions within a supply voltage range of 1.35 V to 3.465 V. It is housed in a VQFN-32 package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Ten LVCMOS outputs for high-density clock distribution
• Supports diverse input standards: CML, HCSL, LVCMOS, LVDS, LVPECL, and SSTL
• Wide supply voltage operation from 1.35 V to 3.465 V
• Maximum operating frequency of 200 MHz

Applications

• Clock distribution networks requiring multiple LVCMOS loads
• Systems interfacing between differential clock sources and LVCMOS logic
• Industrial equipment requiring robust clock buffering across wide voltage ranges

Procurement Notes

Verify the specific suffix LDF1 corresponds to the cut-tape or reel packaging configuration required for assembly. Confirm that the VQFN-32 package dimensions align with the PCB footprint design. Ensure the input signal levels match one of the supported standards (CML, HCSL, LVCMOS, LVDS, LVPECL, SSTL) to guarantee proper operation within the specified 200 MHz limit.

Selection Notes

Select this component when a single clock source must drive ten LVCMOS destinations. It serves as an interface between various differential input formats and standard CMOS logic. Consider the 1.35 V minimum supply voltage if the system operates at lower power rails compared to standard 3.3 V designs. The 200 MHz maximum frequency limits its use in high-speed PCIe or Ethernet applications requiring higher jitter performance or faster speeds.

Part Context

This part belongs to the ZL40241 series of clock buffers. It is distinct from other ZL402x family members which may offer different output counts, such as the six-output ZL40251, or different technologies like the four-output LVDS ZL40215. The ZL40241 specifically targets applications needing ten LVCMOS outputs.

Replacement Considerations

Direct replacements within the same manufacturer line include variants with different packaging options, such as tray-packaged versions if available. Cross-manufacturer equivalents would require matching the ten-output LVCMOS specification, 200 MHz frequency, and compatible input voltage ranges.
