ZL30312GKG

Overview

The ZL30312GKG is an application-specific clock and timing integrated circuit manufactured by Microchip Technology. It is designed for timing-over-packet applications, supporting IEEE 1588 and SyncE standards. The device is intended for use in Ethernet, SONET, and Stratum network environments. It features a 256-pin TEBGA package with surface mount installation. The operational temperature range spans from -40°C to +85°C. This component serves as a specialized solution for precise synchronization in telecommunications infrastructure.

Feature Summary

• Supports Timing-over-Packet (ToP) and Synchronous Ethernet (SyncE) protocols
• Designed for high-precision synchronization in Ethernet and SONET networks
• Compatible with Stratum level timing requirements

Applications

• Ethernet network synchronization
• SONET/SDH timing distribution
• Stratum level clock management systems

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct factory channels. Confirm the specific package variant and revision status prior to ordering. Ensure compliance with RoHS directives if required by your supply chain regulations. Check for any obsolescence notices or lifecycle changes directly on the manufacturer's official website before finalizing procurement plans.

Selection Notes

Select this component when precise timing-over-packet synchronization is required for Ethernet or SONET infrastructure. Consider the 256-pin BGA package constraints for PCB layout and thermal management. Evaluate compatibility with existing IEEE 1588 and SyncE implementations in your network design. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to Microchip's Application Specific Clock & Timer ICs category. It is distinct from general-purpose oscillators or PLLs, focusing specifically on packet-based timing delivery. The ZL30312 series addresses the growing need for synchronization in modern packet-switched networks without dedicated timing lines.

Replacement Considerations

The ZL30312GKG2 is listed as a direct substitute. Verify pinout and functional equivalence before replacement. No other public substitutes are confirmed.
