ZL40220LDF1

Overview

The ZL40220LDF1 is a low-power clock fanout buffer manufactured by Microchip Technology. It accepts two differential or single-ended inputs and provides six identical output drivers. The device supports multiple output standards including LVPECL, LVDS, CML, HCSL, and LVCMOS. It operates at maximum input frequencies up to 750 MHz with a supply voltage range of 2.375 V to 3.465 V. The component features ultra-low additive jitter compliant with the Intel DB2000QL standard and includes glitch-free switching capabilities. It is housed in a 32-VFQFN exposed pad package and functions within an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the input signal levels are compatible with the selected output logic family before implementation. Ensure the design accounts for the specified supply voltage range and thermal characteristics within the industrial temperature limits defined for this component.

Selection Notes

Select this component when a dual-input fanout buffer with multi-standard output support is required. It is suitable for designs needing compliance with Intel DB2000QL jitter specifications. Consider the 32-VFQFN package constraints and the 750 MHz frequency limit relative to the target application's timing requirements.
