ZL50012QCG1

Overview

The ZL50012QCG1 is a digital bus switch integrated circuit manufactured by Microchip Technology. It provides a 512-channel by 512-channel non-blocking switching matrix operating at data rates of 2.048 Mb/s, 4.096 Mb/s, or 8.192 Mb/s. The device supports rate conversion between ST-BUS inputs and outputs, allowing per-stream selection of input and output data rates which may differ. It operates on a single 3V to 3.6V supply voltage with a maximum supply current of 250mA. The component is housed in a 144-LBGA package measuring 13x13 mm and is rated for an industrial temperature range of -40°C to 85°C.

Feature Summary

• Provides a 512 x 512 channel non-blocking digital switch architecture for TDM applications.
• Supports flexible rate conversion between ST-BUS inputs and outputs with independent data rate selection.
• Integrates per-stream high-impedance control outputs for specific output stream management.

Applications

• Telecommunications network synchronization and switching infrastructure
• Digital cross-connect systems requiring flexible TDM routing
• Rate conversion interfaces between different serial TDM streams

Procurement Notes

Verify the exact suffix QCG1 against official Microchip documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing PCB footprints for the 144-LBGA (13x13mm) package before procurement.

Selection Notes

Select this component when a large-scale non-blocking digital switch is required for E1/T1/J1 signal processing. Compare against the ZL50010GDG2 if enhanced DPLL jitter attenuation is needed instead of pure switching. Verify that the 3V to 3.6V supply requirement matches the system power design constraints.

Part Context

This part belongs to the ZL50012 family of flexible digital switches designed for telecom applications. It shares functional similarities with the ZL50010 but lacks the integrated DPLL found in that variant. The QCG1 suffix denotes the specific commercial/industrial temperature grade and LBGA packaging configuration offered by Microchip.

Replacement Considerations

The ZL50010GDG2 offers similar switching capabilities but includes an integrated Digital Phase-Locked Loop (DPLL). Direct substitution requires evaluating whether the additional jitter attenuation features are necessary for the specific application design.
