ZL40204LDG1

Overview

The ZL40204LDG1 is a clock buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It features a 1:6 fanout ratio with LVPECL outputs and includes external termination capabilities. The device supports input formats including CML, HCSL, LVCMOS, LVDS, and LVPECL. It operates within a supply voltage range of 2.375V to 3.465V and functions at frequencies up to 750 MHz. The component is housed in a 32-VFQFN package with an exposed pad, suitable for surface-mount installation across industrial temperature ranges.

Feature Summary

• 1:6 Fanout Buffer Configuration
• LVPECL Output Interface
• External Termination Support
• Multi-Format Input Compatibility (CML, HCSL, LVCMOS, LVDS, LVPECL)

Applications

• High-speed data acquisition systems
• Telecommunications infrastructure
• Test and measurement equipment

Procurement Notes

Verify the specific suffix LDG1 against the official datasheet to confirm package type and operating temperature range. Ensure compatibility with existing PCB footprint designs for the 32-VFQFN enclosure. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a single differential or single-ended clock source requires distribution to six LVPECL loads. Confirm that the system power supply aligns with the 2.375V to 3.465V operational window. Evaluate trace impedance matching requirements for LVPECL signaling integrity at target frequencies up to 750 MHz.

Part Context

This part belongs to the ZL402xx series of clock buffers from Microchip Technology. It shares architectural similarities with variants like the ZL40205LDG1 but differs in output count and specific interface configurations. The series is engineered for low skew and jitter performance in complex timing networks.

Replacement Considerations

Direct pin-to-pin replacements may include other members of the ZL402xx family, such as the ZL40205LDG1, provided the 1:6 ratio and LVPECL outputs match the design requirements. Verify electrical parameters and package dimensions before substitution.
