ZL40215LDF1

Overview

The ZL40215LDF1 is a clock buffer manufactured by Microchip Technology, functioning as a 1:4 LVDS fanout buffer with integrated termination. It operates within a supply voltage range of 2.375 V to 3.465 V and supports maximum input frequencies up to 750 MHz. The device features a maximum propagation delay of 2 ns and is housed in a QFN-16 package. Designed for surface mount installation, it functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• 1:4 LVDS Fanout Buffer Configuration
• Integrated Termination Resistors
• Maximum Input Frequency of 750 MHz
• QFN-16 Surface Mount Package

Applications

• Clock distribution networks requiring LVDS signaling
• High-speed digital systems needing buffered clock signals
• Telecommunications equipment utilizing low-voltage differential signaling

Procurement Notes

Verify the specific suffix 'LDF1' against official Microchip documentation to confirm package type and termination specifications. Ensure compatibility with the required 2.375 V to 3.465 V power supply rails. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent damage during manufacturing processes.

Selection Notes

Select this component when a single clock source needs to drive four LVDS loads with integrated impedance matching. Compare against other models in the ZL402xx series if different output ratios or signal standards are required. Verify that the 750 MHz maximum frequency meets the system's timing requirements and that the QFN-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ZL402xx family of clock buffers and fanout drivers from Microchip Technology. These devices are designed to provide high-performance clock distribution solutions for various digital applications. The ZL40215 variant specifically targets LVDS applications with integrated termination to simplify board design and improve signal integrity.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified pin-compatible alternatives. Ensure any substitute maintains the 1:4 LVDS configuration and QFN-16 package. Verify that electrical parameters such as propagation delay and supply voltage ranges remain compatible with the existing design.
