ZL30102QDG1

Overview

The ZL30102QDG1 is a T1/E1 system synchronizer manufactured by Microchip Technology, designed for precise clock synchronization in telecommunications networks. It features ten outputs with a maximum output frequency of 65.536 MHz and supports a maximum input frequency of 16.384 MHz. The device operates on a single 3.3 V supply voltage, drawing 73 mA during operation. Housed in a TQFP-64 package, it functions within an industrial temperature range of -40°C to +85°C. This component serves as a dedicated clock generator and support product for maintaining signal integrity in T1/E1 infrastructure.

Feature Summary

• Provides 10 synchronized clock outputs for T1/E1 systems
• Supports maximum output frequency up to 65.536 MHz
• Operates on a 3.3 V power supply with 73 mA current consumption
• Available in a TQFP-64 surface-mount package

Applications

• T1/E1 network synchronization
• Telecommunications timing cards
• Clock distribution in digital transmission systems

Procurement Notes

Verify the specific ordering suffix QDG1 against the official Microchip datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the TQFP-64 form factor. Confirm that the 3.3 V supply requirement aligns with the target system design before procurement.

Selection Notes

Select this component when designing for T1/E1 synchronization requirements needing multiple low-frequency outputs. Compare against higher-frequency synthesizers if speeds exceed 65.536 MHz are required. Verify that the TQFP-64 package fits the assembly constraints and that the -40°C to +85°C range meets environmental specifications.

Part Context

This part belongs to the ZL301xx series of clock generators and synchronizers from Microchip. It is distinct from higher-speed SyncE network synchronizers like the ZL80032 or ZL30731, which offer GHz-level frequencies. The ZL30102 is specialized for traditional TDM-based telecom interfaces rather than packet-switched Ethernet timing.

Replacement Considerations

Check for direct pin-compatible alternatives within the ZL301xx family. Verify if upgraded models like the ZL30151 offer similar T1/E1 functionality with enhanced features. Ensure any substitute maintains the 10-output configuration and 65.536 MHz limit.
