• Integrates twenty-four dedicated transceivers for direct media attachment
• Operates in extended industrial temperature environments up to 125°C

Telecom Applications

• Carrier Ethernet network infrastructure equipment
• High-density enterprise switching platforms
• Telecommunications aggregation nodes requiring mixed 1G and 10G connectivity

Telecom Procurement Notes

Verify the lifecycle status before procurement as the component is designated as Not Recommended for New Designs (NRND). Confirm that the FCBGA package and humidity sensitivity requirements align with assembly capabilities. Ensure compatibility with existing MIIM and SGMII interface designs. Review the official datasheet for pinout and electrical specifications to prevent integration errors in new production runs.

Telecom Selection Notes

Select this component when a fixed topology of twenty-four 1G and four 10G ports is required for carrier-grade applications. Consider the extended temperature range if deployment occurs in harsh industrial environments. Evaluate the FCBGA package constraints regarding PCB layout and thermal management. Verify that the integrated transceivers meet the specific physical layer requirements without needing external PHYs.

Telecom Part Context

The VSC7460YIH belongs to the Jaguar-1 family of Ethernet switches from Microchip Technology. This series targets high-performance networking solutions requiring significant port density. The YIH suffix typically denotes specific package and temperature grade variations within the Jaguar product line. It serves as a core switching engine for complex network architectures demanding both gigabit and ten-gigabit throughput.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on port count, speed, and package compatibility. Consult Microchip Technology for current portfolio recommendations to replace legacy Jaguar-1 designs.
