ZL30119GGG2

Overview

The ZL30119GGG2 is a SONET/SDH telecommunications clock synchronizer manufactured by Microchip Technology. It operates within a supply voltage range of 2.97V to 3.63V and supports a maximum frequency of 622.08MHz. The device features one circuit with an input-to-output ratio of 11:14, accepting LVCMOS inputs and providing LVCMOS or LVPECL outputs. Packaged in a 100-CABGA (9x9) surface-mount format, it functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Synchronizes with standard telecom system references
• Synthesizes protected telecom line interface clocks compliant with Telcordia GR-253-CORE and ITU-T G.813
• Internal APLL provides standard output clock

Applications

• SONET/SDH OC-48/OC-192 line card synchronization
• Telecommunications network timing systems

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm the specific suffix 'GGG2' matches design requirements, as package or marking variations may exist. Check for Product Change Notifications (PCN) regarding manufacturing updates. Ensure ESD handling protocols are followed during installation due to the fine-pitch CABGA package.

Selection Notes

Select this model for applications requiring strict compliance with Telcordia GR-253-CORE and ITU-T G.813 standards. The 11:14 input-to-output ratio suits specific SONET/SDH frequency multiplication needs. Verify that the single-output configuration meets system timing requirements compared to multi-output alternatives in the ZL301xx family.

Part Context

The ZL30119 belongs to the ZL301xx series of SONET/SDH line card synchronizers. This series includes variants like the ZL30117 and ZL30120, which share similar telecom-focused functionalities but differ in pin counts, output configurations, and specific frequency ratios tailored for different network interface speeds.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the ZL301xx family, such as the ZL30117 or ZL30120, for potential compatibility based on specific SONET/SDH layer requirements and pinout similarities.
