VSC8491EV

Overview

The VSC8491EV is an evaluation board for the Microsemi VSC8491, a dual 10 GbE SerDes PHY. It supports RXAUI/XAUI to SFP+ and KR interfaces with integrated VeriTime IEEE 1588v2 timing and MACsec security. The device operates at 9.95 Gbps WAN and 10.3 Gbps LAN speeds, plus 1.25 Gbps Ethernet. Typical power consumption is 1.15 W per bidirectional channel, utilizing 1.2 V and 1.0 V core supplies with a 2.5 V TTL supply.

Feature Summary

Integrates VeriTime technology for high-precision IEEE 1588v2 synchronization
Provides hardware-based MACsec encryption compliant with IEEE 802.1AE
Supports adaptive equalization and programmable transmitter pre-emphasis
Includes comprehensive BIST functionality with loopback and pattern generation

Applications

Multiple-port RXAUI/XAUI to SFI/SFP+ line cards or NICs
10GBASE-KR compliant backplane transceivers
Carrier Ethernet networks requiring precise timing
Secure data center-to-data center interconnects
10 GbE switch cards, router cards, and NICs

Procurement Notes

Verify the specific revision level of the VSC8491EV reference design against the latest Microsemi documentation before integration. Confirm that the host system provides the required 1.2 V, 1.0 V, and 2.5 V power rails. Ensure thermal management meets the typical 1.15 W per channel dissipation requirements during validation testing.

Selection Notes

Select this evaluation tool when validating designs requiring seamless integration of IEEE 1588v2 timing and MACsec security within a single PHY. It is suitable for prototyping applications demanding low-latency synchronization and secure data transmission across various Ethernet standards including SFP+ and 10GBASE-KR.
