ZL30634LDG1

Overview

The ZL30634LDG1 is a system synchronizer featuring up to five independent clock channels, ten inputs, and twenty outputs. It supports any-to-any frequency conversion with input frequencies from 0.5 Hz to 1250 MHz and output frequencies up to 750 MHz. The device integrates up to eight DPLLs for timing compliance with ITU-T G.8262 and G.813 standards. Output jitter is typically 100 fsRMS at 156.25 MHz. It operates on 1.8V and 3.3V core supplies within a 64-lead VQFN package.

Feature Summary

• Up to five independent clock channels with any-to-any frequency conversion
• Supports up to 10 differential or single-ended inputs and 20 CMOS outputs
• Integrates up to 8 DPLLs for telecom timing compliance (ITU-T G.8262, G.813)
• Typical output jitter of 100 fsRMS at 156.25 MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product brief to confirm pinout and feature availability. Confirm RoHS compliance status and lead-free specifications directly with Microchip Technology Inc. distributors before procurement.

Selection Notes

Select this component when requiring up to five independent clock channels with high-density I/O. Ensure the design accommodates the 64-lead VQFN package dimensions. Verify that the required input/output voltage levels align with the 1.8V and 3.3V core supply capabilities.

Part Context

This part belongs to the ZL30631-ZL30635 family of system synchronizers. The ZL30634 variant specifically provides five independent clock channels, distinguishing it from lower-channel variants in the series while sharing the same package and interface architecture.

Replacement Considerations

Consult the official product brief for confirmed substitute part numbers within the ZL3063x family. Verify channel count and I/O compatibility before substituting.
