ZL40221LDG1

Overview

The ZL40221LDG1 is a clock buffer manufactured by Microchip Technology, housed in a 32-VFQFN package with an exposed pad. It operates as a fanout buffer and multiplexer with a 2:6 input-to-output ratio. The device supports differential inputs and outputs, accepting CML, HCSL, LVCMOS, LVDS, or LVPECL signals. It delivers LVDS outputs at a maximum frequency of 750 MHz. Electrical operation requires a supply voltage between 2.375 V and 3.465 V, and the component functions within a temperature range of -40°C to 85°C.

Feature Summary

• 2:6 Input-to-Output Ratio
• Maximum Frequency of 750 MHz
• Supports CML, HCSL, LVCMOS, LVDS, and LVPECL Inputs
• LVDS Output Configuration

Applications

• Clock distribution networks requiring signal buffering
• Multiplexing multiple clock sources for system synchronization
• Converting various logic levels to LVDS for high-speed transmission

Procurement Notes

Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Confirm that the 32-QFN package dimensions match the target PCB footprint. Ensure the design accommodates the required 2.375 V to 3.465 V power supply rails and thermal dissipation needs for the exposed pad.

Selection Notes

Select this component when a 2:6 fanout ratio with LVDS outputs is required. It is suitable for applications needing to accept diverse input standards like CML or LVPECL and convert them to LVDS. Verify that the 750 MHz maximum frequency meets the system timing requirements and that the operating temperature range covers the intended environment.

Part Context

This part belongs to the ZL4022x series of clock buffers from Microchip Technology. It shares functional similarities with other models in the family, such as the ZL40222, but differs in its specific input-to-output configuration. The LDG1 suffix denotes the specific packaging and temperature grade variant within this product line.

Replacement Considerations

The ZL40221LDF1 is a parameter-equivalent alternative offering the same 2:6 ratio and 750 MHz performance in a tape-and-reel package instead of a tray.
