VSC8494YJE-12

Telecom Overview

The VSC8494YJE-12 is a dual and quad 10 Gigabit Ethernet PHY transceiver manufactured by Microchip Technology. It integrates OTN-FEC capabilities for enhanced signal integrity over extended distances. The device supports four transceivers with data rates up to 10 Gb/s. It utilizes XFI/SFI interface types for high-speed connectivity. The component is housed in a 780-ball FCBGA package designed for surface mount installation. This IC belongs to the Communication & Networking ICs subcategory under Ethernet Transceivers.

Telecom Feature Summary

• Integrates On-The-Wire Forward Error Correction (OTN-FEC) functionality to improve link reliability.
• Supports both dual and quad channel configurations for flexible deployment.
• Features integrated Clock Data Recovery (CDR) circuits within the transceiver blocks.

Telecom Applications

• Telecommunications infrastructure requiring 10G Ethernet connectivity
• Data center interconnects utilizing OTN standards
• High-performance networking equipment needing FEC-enhanced links

Telecom Procurement Notes

This component has reached End-of-Life status, as indicated by the manufacturer's discontinuation notification. Availability is restricted to existing stock or surplus markets. Verification of the specific lot date code and authenticity is critical due to the discontinued lifecycle stage. Buyers should confirm the exact revision level against current design requirements before acquisition.

Telecom Selection Notes

Engineers replacing this part must account for its discontinued status when designing new systems. The VSC8494 series offers specific OTN-FEC integration that may not be present in all standard 10G PHYs. Designers should verify pin compatibility and power supply requirements if substituting with other Microchip devices like the VSC8484, noting differences in package type and interface support.

Telecom Part Context

The VSC8494YJE-12 is part of Microchip's VSC84xx family of 10 Gigabit Ethernet PHYs. This family focuses on providing robust physical layer solutions for carrier-grade applications. The YJE suffix typically denotes specific packaging and temperature range characteristics within the broader product line.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements require careful evaluation of functional equivalence, particularly regarding OTN-FEC support and interface compatibility.
