ZL40223LDF1

Overview

The ZL40223LDF1 is a clock buffer and fanout buffer manufactured by Microchip Technology. It features a 2:8 input-to-output configuration, converting two differential inputs into eight LVDS outputs. The device integrates internal termination resistors to simplify board design. It operates with a maximum frequency of 750 MHz and supports supply voltages ranging from 2.375 V to 3.465 V. The component is housed in a 32-VFQFN package with an exposed pad, suitable for surface-mount applications within an operating temperature range of -40°C to 85°C.

Feature Summary

• 2:8 LVDS Fanout Buffer Configuration
• Integrated Internal Termination Resistors
• Maximum Frequency of 750 MHz
• 32-VFQFN Package with Exposed Pad

Applications

• High-speed digital signal distribution
• Clock tree generation in communication systems
• Data acquisition systems requiring low-skew buffering

Procurement Notes

Verify the specific suffix 'LDF1' against the official Microchip datasheet to confirm the presence of internal termination and the reel packaging format. Ensure compatibility with the required 32-VFQFN footprint and exposed pad thermal requirements during procurement planning.

Selection Notes

Select this component when a 2:8 LVDS fanout ratio is required with integrated termination to reduce external component count. Compare against the ZL40222LDG1 if external termination is preferred or if tray packaging is necessary instead of the reel format associated with the LDF1 suffix.

Part Context

This part belongs to the SmartBuffer family of clock buffers. It shares architectural similarities with other ZL402xx series devices but is distinct in its 2:8 topology and LVDS output specification. It serves as a specialized solution for distributing clock signals in high-density PCB layouts.

Replacement Considerations

The ZL40222LDG1 offers similar 2:8 LVDS functionality but utilizes external termination resistors and comes in a tray package. Verify pinout compatibility and termination requirements before substituting.
