ZL40230LDG1

Overview

The ZL40230LDG1 is a clock fanout buffer manufactured by Microchip Technology, housed in a 48-VQFN package. It features three independent sections, each providing ten outputs for a total of thirty output channels. The device supports LVPECL, LVDS, and HCSL output logic levels. It accepts crystal, differential, or LVCMOS input signals with a maximum input frequency of 1.6 GHz. The component operates within a supply voltage range of 1.35 V to 3.465 V and maintains a maximum propagation delay of 2.07 ns across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides three independent buffering sections with ten outputs per section.
• Supports multiple output logic standards including LVPECL, LVDS, and HCSL.
• Accepts diverse input types such as crystal, differential, and LVCMOS signals.

Applications

• High-speed data acquisition systems requiring precise clock distribution
• Telecommunications infrastructure utilizing SONET/SDH protocols
• Test and measurement equipment demanding low-jitter timing

Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to confirm exact electrical characteristics and pinout configuration. Ensure that the selected variant matches the required output logic levels and input signal compatibility for the target application design.

Selection Notes

Select this component when a high channel count with mixed logic level support is required. Evaluate the trade-off between the thirty-output capacity and the 1.6 GHz input limit. Confirm that the 48-VQFN package dimensions fit the available PCB real estate constraints.

Part Context

This part belongs to the ZL402x series of clock fanout buffers from Microchip Technology. The series offers various output configurations designed to distribute reference clocks with low skew and minimal additive jitter. These devices are intended to replace discrete buffer solutions in complex timing architectures.

Replacement Considerations

Cross-reference the ZL40231LDG1 for similar functionality with potential pinout variations. Verify compatibility with the ZL40234LDG1 if different output counts are acceptable. Consult official substitution lists for confirmed equivalents.
