ZL30635LDG1

Overview

The ZL30635LDG1 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 from 0.5 Hz to 750 MHz. The device includes 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 voltages within a 64-lead VQFN package.

Feature Summary

• Up to five independent clock channels with any-to-any frequency conversion capability
• Supports up to 10 differential or single-ended inputs and up to 20 CMOS or 10 differential outputs
• Includes up to 8 DPLLs for high-resolution holdover and hitless reference switching
• Features MiToDSync and MiToDBasic interfaces for time-of-day information transfer

Applications

• Central system timing for SyncE and IEEE 1588 networks
• 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 official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required SPI or I2C interface configurations during procurement planning.

Selection Notes

Select this model when requiring up to five independent clock channels and support for up to 10 inputs. Verify that the maximum output frequency of 750 MHz meets system requirements. Confirm power supply voltage availability for both 1.8V and 3.3V domains.

Part Context

This component belongs to the ZL3063x family of system synchronizers. It shares architectural similarities with models like ZL30631 through ZL30634, differing primarily in the number of integrated DPLLs and synthesizer channels available per specific part number.

Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Cross-model generic features should not be assumed to apply directly without verifying specific parameter differences.
