ZL30733ALDG1

Overview

The ZL30733ALDG1 is a network synchronizer from the Microchip ZL3073x family, housed in a 64-lead VQFN package. It provides up to five independent clock channels with support for up to ten differential or single-ended inputs and twenty CMOS outputs. The device accepts input frequencies ranging from 0.5 Hz to 1250 MHz and generates output frequencies from 0.5 Hz to 750 MHz. It features up to eight Digital Phase-Locked Loops (DPLLs) and synthesizers capable of any-to-any frequency conversion with typical output jitter of 100 fsRMS at 156.25 MHz. Operating voltages are 1.8V and 3.3V.

Feature Summary

• Up to five independent clock channels with any-to-any frequency conversion
• Supports up to ten inputs (differential/single-ended) and twenty CMOS outputs
• Includes up to eight DPLLs for precise phase alignment and holdover
• Compliant with ITU-T G.8262, G.8263, and IEEE 1588-2008 standards

Applications

• Central system timing for SyncE and SyncE+1588 carrier-grade systems
• Wireless base stations including 3G, W-CDMA, 4G/LTE, LTE-A, and 5G
• Remote Radio Units (RRU), small cells, and wireless backhaul networks

Procurement Notes

Verify the specific ordering suffix 'A' against official documentation to confirm manufacturing revision details. Confirm availability through authorized distributors as supply status varies. Ensure compliance with RoHS requirements and check for moisture sensitivity levels prior to soldering.

Selection Notes

Select this model when requiring up to five clock channels and up to ten inputs. Verify that the required number of outputs does not exceed the twenty CMOS limit. Ensure the application supports the 9 mm x 9 mm VQFN package dimensions and pitch specifications.

Part Context

This component belongs to the ZL30731-ZL30735 product family. The ZL30733 variant specifically offers three independent clock channels within the broader family capabilities of up to five channels. It shares common architectural features such as internal flash memory and MiToDSync interfaces with sibling models.

Replacement Considerations

Compatible substitutes within the same family include ZL30731LDG1, ZL30732LDG1, ZL30734LDG1, and ZL30735LDG1. Selection depends on the specific requirement for the number of independent clock channels and available I/O pins.
