ZL40205LDG1

Overview

The ZL40205LDG1 is a single-circuit clock fanout buffer manufactured by Microchip Technology, housed in a 32-VFQFN package with an exposed pad. It provides a 1:6 input-to-output ratio and supports a maximum frequency of 750 MHz. The device accepts differential or single-ended inputs including CML, HCSL, LVCMOS, LVDS, and LVPECL, while delivering LVPECL outputs. It operates on a supply voltage ranging from 2.375 V to 3.465 V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports multiple input formats: CML, HCSL, LVCMOS, LVDS, and LVPECL
• Delivers six LVPECL output channels
• Maximum operating frequency of 750 MHz
• Available in a 32-QFN (5x5 mm) surface-mount package

Applications

• High-speed data acquisition systems requiring clock distribution
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Industrial automation control units

Procurement Notes

Verify the specific suffix LDG1 against the manufacturer's current datasheet to confirm pinout and electrical specifications. Confirm moisture sensitivity level (MSL 3) requirements for storage and reflow soldering profiles prior to assembly. Ensure the ordering quantity aligns with the standard factory packaging quantity of 490 units per tray.

Selection Notes

Select this component when a 1:6 fanout ratio with LVPECL outputs is required. Verify that the system power supply remains within the 2.375 V to 3.465 V range. Consider alternative models such as the ZL40208LDG1 if LVPECL inputs are also needed, or the ZL40210LDG1 for an 8-output configuration.

Part Context

This part belongs to the ZL402xx series of SmartBuffer clock buffers from Microchip Technology. It shares the same 32-VFQFN footprint and general electrical characteristics with siblings like the ZL40208LDG1 and ZL40210LDG1, differing primarily in input/output configuration and supported input signal types.

Replacement Considerations

Direct functional substitutes include the ZL40208LDG1 and ZL40210LDG1, which share the same package and voltage range but offer different output counts or input capabilities. Cross-reference the specific input signal requirements before substitution.
