ZL40211LDF1

Overview

The ZL40211LDF1 is a clock buffer manufactured by Microchip Technology, housed in a QFN-32 package. It operates as a 2:8 LVPECL fanout buffer with input termination. The device supports a maximum input frequency of 750 MHz and features a maximum propagation delay of 2 ns. It functions within a supply voltage range of 2.375 V to 3.465 V and operates at temperatures from -40 °C to +85 °C.

Feature Summary

• Provides two inputs and eight outputs for LVPECL clock distribution
• Integrates internal input termination for signal integrity
• Supports high-frequency operation up to 750 MHz

Applications

• High-speed digital system clock distribution
• Data converter timing synchronization
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'F1' against the official datasheet to confirm the exact pinout and termination configuration. Ensure the QFN-32 package dimensions match the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly process before procurement.

Selection Notes

Select this component when a 2-to-8 LVPECL fanout buffer with integrated input termination is required. Consider the 750 MHz frequency limit and 2 ns propagation delay for timing-critical paths. Evaluate the QFN-32 package size and thermal characteristics against board space constraints and operating temperature ranges.

Part Context

This part belongs to the ZL4021 series of clock buffers from Microchip Technology. It is designed for applications requiring precise clock distribution with low skew and jitter. The series includes variants with different output counts and signaling standards, such as LVDS or LVPECL, tailored for various high-speed digital designs.

Replacement Considerations

Consult the official datasheet for direct cross-references. Verify that any substitute maintains the 2:8 LVPECL configuration, QFN-32 package, and 750 MHz operational capability. Check for compatibility with existing input termination requirements.
