ZL30310GKG2

Overview

The ZL30310GKG2 is a timing-over-packet integrated circuit manufactured by Microchip Technology. It is designed for synchronization applications in Ethernet and Stratum networks, supporting IEEE 1588 Precision Time Protocol (PTP) and SyncE standards. The device features an internal Phase-Locked Loop (PLL) to generate precise clock outputs from packet-based inputs. It operates within a temperature range of -40°C to 85°C and is housed in a 256-BGA package measuring 17x17 mm. The maximum output frequency supported is 125 MHz.

Feature Summary

• Supports Timing-over-Packet protocols including IEEE 1588 PTP and SyncE
• Integrated PLL for clock generation and jitter attenuation
• Designed for Ethernet and Stratum network synchronization requirements
• Available in a 256-BGA surface-mount package

Applications

• Ethernet network synchronization infrastructure
• Stratum-level timing distribution systems
• Telecommunications equipment requiring precise clock recovery

Procurement Notes

Verify the specific suffix 'GKG2' against official Microchip documentation to confirm pinout, voltage, and package dimensions. Ensure compatibility with existing PCB layouts due to the 256-BGA form factor. Confirm RoHS compliance status through current datasheets before procurement.

Selection Notes

Select this component when designing systems requiring high-precision timing over packet-switched networks. Verify that the 125 MHz maximum frequency meets system clock requirements. Ensure thermal management solutions are adequate for the operating temperature range of -40°C to 85°C.

Part Context

This part belongs to the ZL3031x family of timing-over-packet synchronizers. It shares functional similarities with other models in the series but differs in package type and specific electrical characteristics defined by the GKG2 suffix. It serves as a key component for maintaining time synchronization in modern telecommunications networks.
