ZL50015GAG2

Overview

The ZL50015GAG2 is a digital bus switch IC manufactured by Microchip Technology, housed in a 256-BGA (17x17) surface-mount package. It operates on a supply voltage ranging from 1.71V to 1.89V with a typical supply current of 150mA and supports an operating temperature range of -40°C to 85°C. The device functions as a non-blocking digital Time Division Multiplex (TDM) switch supporting up to 1024 channels at rates of 4.096, 8.192, or 16.384 Mbps. It integrates a Digital Phase-Locked Loop (DPLL) that exceeds Telcordia GR-1244-CORE Stratum 4E specifications, providing output clocks with less than 1 ns of jitter.

Feature Summary

• Integrates a high-performance Digital Phase-Locked Loop (DPLL) compliant with Telcordia GR-1244-CORE Stratum 4E standards for precise timing synchronization.
• Provides a 1024-channel by 1024-channel non-blocking digital TDM switching matrix capable of handling multiple port speeds including 2.048, 4.096, 8.192, and 16.384 Mbps.
• Features sixteen serial TDM input streams and sixteen serial TDM output streams for flexible signal routing.

Applications

• Telecommunications infrastructure requiring Stratum 4E clock synchronization
• Digital Time Division Multiplex (TDM) network switching systems
• High-speed data routing in communication equipment

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on surplus distributors rather than direct manufacturing channels. Buyers must confirm the authenticity of existing stock due to the discontinuation status. Reviewing the official EOL Product Discontinuance Notification is recommended to understand the final purchase dates and support timelines before committing to procurement.

Selection Notes

Designers should evaluate the ZL50015GAG2 primarily for its integrated DPLL capabilities meeting Stratum 4E requirements within a dense BGA footprint. Consider the specific voltage constraints of 1.71V to 1.89V during power budget analysis. Due to the EOL status, alternative components with similar channel counts and jitter performance should be identified for long-term production viability. Ensure the 256-BGA package fits the thermal and spatial constraints of the target PCB layout.

Part Context

The ZL50015 series belongs to Microchip's portfolio of enhanced digital switches designed for telecom applications. This specific model represents a high-density solution integrating switching and timing functions. It is part of a lineage of devices aimed at simplifying system architecture by combining TDM switching with precision clock generation in a single integrated circuit.

Replacement Considerations

As the ZL50015GAG2 is discontinued, engineers should consult Microchip's official obsolescence notices for recommended replacement parts. Potential substitutes must match the 256-BGA form factor, Stratum 4E DPLL compliance, and 1024-channel switching capacity. Verify pin-to-pin compatibility and electrical characteristics against the original datasheet specifications.
