ZL30146GGG

Overview

The ZL30146GGG is a clock generator integrated circuit manufactured by Microchip Technology, designed for Ethernet, SONET/SDH, and telecommunications applications. It features a single output capable of generating frequencies up to 622.08 MHz. The device incorporates an internal Phase-Locked Loop (PLL) with a specified input-to-output ratio of 6:4. It supports differential outputs while utilizing a single clock input. The component operates within a temperature range of -40°C to 85°C and is housed in a 64-CABGA package measuring 9x9 mm.

Feature Summary

• Generates clock signals up to 622.08 MHz for high-speed data transmission
• Integrates a PLL with a 6:4 input-to-output frequency ratio
• Supports differential output configurations for signal integrity
• Operates reliably in industrial temperatures from -40°C to 85°C

Applications

• Ethernet network infrastructure equipment
• SONET/SDH synchronous optical networking systems
• Telecommunications base stations and core network gear

Procurement Notes

Verify the specific suffix 'GGG' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the 64-CABGA package dimensions align with the target PCB footprint. Confirm RoHS compliance status through official documentation before integration into production designs.

Selection Notes

Select this component when a precise 622.08 MHz clock source is required for SONET/SDH or Ethernet interfaces. The 6:4 PLL ratio dictates the necessary reference input frequency. Evaluate the 64-CABGA package size constraints and thermal dissipation requirements for the operating environment.

Part Context

This part belongs to the ZL3014x family of clock generators from Microchip. These devices are engineered for telecom-grade timing solutions. The GGG suffix typically denotes the specific package type and material composition, distinguishing it from other variants in the same functional series.

Replacement Considerations

Consult the official Microchip cross-reference guide for verified substitutes. Direct replacements must match the 64-CABGA package, 622.08 MHz output capability, and 6:4 PLL ratio. Generic clock generators may not provide the specific timing characteristics required for SONET/SDH standards.
