ZL50020GAC

Overview

The ZL50020GAC is a digital bus switch integrated circuit manufactured by Microchip Technology. It functions as an enhanced 2K non-blocking digital Time Division Multiplex (TDM) switch. The device supports data rates of 8.192 Mbps and 16.384 Mbps, or combinations of ports running at 2.048, 4.096, 8.192, and 16.384 Mbps. It features 32 serial TDM input streams and 32 serial TDM output streams. The component operates within a supply voltage range of 1.71V to 1.89V with a typical supply current of 120mA. It is designed for surface mount installation in a 256-LQFP package measuring 28x28 mm.

Feature Summary

• Provides 2048 channel by 2048 channel non-blocking switching capability for digital TDM applications.
• Supports flexible per-stream input and output data rate conversion selections across standard TDM rates.
• Features exceptional input clock cycle-to-cycle variation tolerance of 20 ns for all supported rates.

Applications

• Telecommunications network infrastructure equipment
• Digital time division multiplexing systems
• Backplane connections requiring bidirectional output stream configuration

Procurement Notes

Verify the specific suffix GAC against official Microchip documentation to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list discontinued or end-of-life inventory. Request the latest datasheet directly from the manufacturer to ensure compliance with current technical specifications before procurement.

Selection Notes

Select this component when a high-density digital TDM switch is required for telecommunications interfaces. Ensure the system design accommodates the specific 1.71V to 1.89V supply voltage requirement. Verify that the 256-LQFP package dimensions fit the target PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ZL50020 family of enhanced digital switches. It shares core functionality with variants like the ZL50020QCG1 but differs in package type and specific commercial/industrial grade ratings defined by the suffix. It serves as a key interconnect solution for managing multiple TDM streams in complex switching architectures.

Replacement Considerations

Check for direct replacements within the ZL50020 series such as the ZL50020QCG1. Verify package compatibility and electrical parameter alignment before substitution. Consult Microchip for any updated components replacing this specific variant.
