ZL30735LDG1

Overview

The ZL30735LDG1 is a five-channel, ten-output clock synthesizer and jitter cleaner manufactured by Microchip Technology. Designed for network synchronization applications, it supports IEEE 1588 timing protocols. The device accepts differential or single-ended inputs with frequencies up to 1.25 GHz and generates outputs up to 750 MHz in CMOS or differential formats. It operates on a supply voltage ranging from 1.8 V to 3.3 V and is housed in a 64-lead VQFN package.

Feature Summary

• Five input channels supporting any-to-any frequency multiplication
• Ten output clocks with CMOS or differential signaling options
• Integrated jitter cleaning capabilities for signal integrity
• Supports IEEE 1588 Precision Time Protocol (PTP) synchronization

Applications

• Network synchronizers for telecommunications infrastructure
• IEEE 1588 timing card implementations
• High-performance clock distribution systems
• Jitter attenuation in data communication links

Procurement Notes

Verify the specific ordering suffix against the official Microchip datasheet to ensure correct package type and temperature range. Confirm RoHS compliance status through current manufacturer documentation before procurement. Cross-reference the Mouser part number 579-ZL30735LDG1 with the manufacturer's latest release notes to validate availability and revision history.

Selection Notes

Select this component when designing systems requiring multiple synchronized clock outputs derived from diverse input sources. Ensure the design accommodates the 1.8 V to 3.3 V power supply requirements. Verify that the required output frequencies do not exceed the 750 MHz maximum limit. Consider the VQFN-64 thermal performance during PCB layout planning.

Part Context
