ZL50015QCG1

Overview

The ZL50015QCG1 is a digital Time Division Multiplex (TDM) switch manufactured by Microchip Technology, housed in a 256-lead Low-Profile Quad Flat Package (LQFP) measuring 28x28 mm. It supports a non-blocking switching matrix of 1024 channels by 1024 channels. The device operates at data rates of 4.096 Mbps, 8.192 Mbps, and 16.384 Mbps, or utilizes mixed port speeds including 2.048 Mbps. It integrates a Digital Phase-Locked Loop (DPLL) compliant with Telcordia GR-1244-CORE Stratum 4E specifications. The component functions within a supply voltage range of 1.71V to 1.89V and maintains an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides a 1024-channel by 1024-channel non-blocking digital TDM switching architecture.
• Integrates a DPLL exceeding Stratum 4E jitter attenuation standards with less than 1 ns output jitter.
• Supports flexible port configurations allowing combinations of 2.048, 4.096, 8.192, and 16.384 Mbps streams.

Applications

• Telecommunications network infrastructure requiring high-density TDM switching.
• Digital cross-connect systems utilizing Stratum 4E clock synchronization.
• Mixed-rate serial TDM input and output stream processing.

Procurement Notes

Verify the current lifecycle status before design implementation, as this specific part number may be discontinued or subject to limited availability. Confirm that the 256-LQFP package dimensions and pinout align with existing PCB footprints. Ensure that the 1.8V power supply rails meet the specified tolerance for reliable operation.

Selection Notes

Select this component when a large-scale non-blocking TDM matrix is required alongside integrated high-performance clocking. The integrated DPLL eliminates the need for external jitter attenuators in Stratum 4E applications. Verify compatibility with mixed-speed TDM interfaces if deploying ports at varying bit rates simultaneously.

Part Context

This device belongs to the ZL50015 family of enhanced digital switches. It shares architectural similarities with other members like the ZL50018 but offers distinct channel counts and interface capabilities. The QCG1 suffix typically denotes industrial temperature range and specific packaging variations within the Microsemi/Microchip portfolio.

Replacement Considerations

Direct substitutes include other models within the ZL50015 series or the ZL50018 family, provided they match the 256-LQFP package and Stratum 4E requirements. Verify functional equivalence regarding channel count and supported data rates before substitution.
