ZL30733LDG1

Overview

The ZL30733LDG1 is a network synchronizer and clock synthesizer manufactured by Microchip Technology. It features five independent digital phase-locked loop (DPLL) channels and supports up to ten single-ended or differential inputs. The device provides thirty CMOS or differential outputs with a maximum output frequency of 750 MHz. It operates on a supply voltage ranging from 1.8 V to 3.3 V and is housed in a 64-pin VQFN package. Designed for high-performance timing applications, it integrates IEEE 1588 Precision Time Protocol support.

Feature Summary

• Integrates five independent DPLL channels for complex synchronization tasks
• Supports IEEE 1588 PTP protocol for precise time distribution
• Provides 30 outputs with frequencies up to 750 MHz
• Accepts up to 10 differential or single-ended inputs

Applications

• 5G Radio Unit (RU) timing synchronization
• Distributed Unit (DU) and Centralized Unit (CU) networks
• Base station timing cards
• Network equipment requiring ITU-T G.8273.2 compliance

Procurement Notes

Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Check for any Product Change Notifications (PCN) regarding packaging or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when five independent DPLL channels are required for multi-standard synchronization. Ensure the design accommodates the 64-pin VQFN package thermal requirements. Verify that the input signal types match the supported differential and single-ended configurations.

Part Context

This part belongs to the ZL3073x/63x/64x network synchronizer platform designed for 5G infrastructure. It replaces older generations like the ZL30702 series, offering higher integration and lower jitter performance suitable for modern wireless access networks.

Replacement Considerations

The ZL30702LDG6 is listed as an obsolete predecessor. Direct replacement requires verification of pin compatibility and software configuration differences between the legacy ZL30702 and the newer ZL3073x architecture.
