ZL50010/GDC

Overview

The ZL50010 is a flexible 512-channel digital crosspoint switch manufactured by Microchip Technology. It supports non-blocking switching at data rates of 2.048 Mbps, 4.096 Mbps, or 8.192 Mbps. The device integrates an enhanced Digital Phase-Locked Loop (DPLL) that meets Telcordia GR-1244-CORE Stratum 4 specifications. Key electrical parameters include a supply voltage range of 3V to 3.6V and a maximum supply current of 250mA. It operates within a temperature range of -40°C to +85°C. The component is housed in a 144-LBGA package with dimensions of 13x13 mm.

Feature Summary

• Provides 512 x 512 channel non-blocking switching capability for ST-BUS signals.
• Integrates a DPLL for automatic reference switching, jitter attenuation, holdover, and free run functions.
• Supports rate conversion between ST-BUS inputs and outputs with per-stream data rate selection.

Applications

• Telecommunications network synchronization systems
• Digital cross-connect switches
• Jitter attenuation and clock recovery applications

Procurement Notes

Verify the specific ordering suffix against the official Microchip datasheet to confirm pinout and functionality. Ensure the procurement source provides traceability documentation consistent with Microchip's quality standards. Confirm the package type matches the required 144-LBGA form factor for the target design.

Selection Notes

Select this component when a high-density digital crosspoint switch with integrated Stratum 4 timing performance is required. Consider the ZL50010 for designs needing flexible rate conversion between 2.048 Mbps, 4.096 Mbps, and 8.192 Mbps streams without external timing circuitry.

Part Context

The ZL50010 belongs to the ZL50010 family of flexible digital crosspoint switches. It is designed to replace traditional analog-based switching solutions in telecommunications infrastructure, offering higher density and integrated timing capabilities within a single semiconductor package.

Replacement Considerations

Consult the Microchip compatibility matrix for direct pin-to-pin replacements. Verify functional equivalence regarding DPLL performance and channel count if substituting with other members of the ZL500xx series.
