ZL30732ALDG1

Overview

The ZL30732ALDG1 is a network synchronizer from the Microchip ZL3073x family, designed for PTP and SyncE applications. It features up to five independent clock channels with any-to-any frequency conversion capabilities. The device accepts up to ten differential or single-ended inputs ranging from 0.5 Hz to 1250 MHz and provides up to ten differential or twenty CMOS outputs spanning 0.5 Hz to 750 MHz. Typical output jitter is 100 fsRMS at 156.25 MHz (12 kHz to 20 MHz bandwidth). Core power consumption is less than 0.9 W. It integrates up to eight DPLLs, supports MiToDSync interfaces, and operates on 1.8 V and 3.3 V supplies within a 64-lead VQFN package.

Feature Summary

• Up to five independent clock channels with any-to-any frequency conversion and zero ppm error.
• Supports up to ten inputs (0.5 Hz to 1250 MHz) and up to ten differential or twenty CMOS outputs (0.5 Hz to 750 MHz).
• Integrates up to eight DPLLs with high-resolution holdover averaging and hitless reference switching.
• Typical output jitter of 100 fsRMS at 156.25 MHz with core power consumption under 0.9 W.

Applications

• Central system timing ICs for SyncE, SyncE+1588, routers, switches, and OTN systems.
• Wireless base stations including 3G, W-CDMA, 4G/LTE, LTE-A, and 5G networks.
• Remote Radio Units (RRU), Remote Access Networks (RAN), small cells, and wireless backhaul.

Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm configuration differences such as pinout variations or internal memory settings. Ensure the ordering part number matches the required channel count and output types defined in the product brief. Confirm compliance with relevant ITU-T and IEEE standards for the target synchronization application.

Selection Notes

Select this model based on the requirement for up to five clock channels and support for both physical-layer and packet-network synchronization. Verify that the input frequency range up to 1250 MHz and output range up to 750 MHz meet system specifications. Consider the low jitter performance and power consumption if designing for carrier-grade or wireless infrastructure environments.

Part Context

This component belongs to the ZL30731-ZL30735 family of PTP and SyncE network synchronizers. These devices are engineered for high-performance timing in telecommunications and datacom applications. The family shares common architectural features like multiple DPLLs and synthesizers, differentiated by the number of available channels and I/O configurations.

Replacement Considerations

Other members of the ZL3073x family (ZL30731, ZL30733, ZL30734, ZL30735) share the same package and general functionality but differ in channel counts and I/O availability. Verify pin compatibility and feature requirements before substituting.
