Telecom datasheet and documents for VSC8257EV

VSC8257EV

Telecom Overview

The VSC8257EV is a quad-channel serial-to-serial Ethernet WIS PHY featuring VeriTime technology for IEEE 1588v2 precision timing. It supports 1G and 10G modes, including 10GBASE-KR backplane connectivity with auto-negotiation. The device operates on 1.2V and 1.0V core supplies with a 2.5V TTL supply, consuming approximately 1.2W per bidirectional channel. It integrates built-in self-test (BIST), loopbacks, and flexible clocking for Synchronous Ethernet.

Telecom Feature Summary

VeriTime network timing technology delivering high-accuracy IEEE 1588v2 support
Dual-sided 10GBASE-KR functionality with adaptive equalization and pre-emphasis
Integrated BIST and flexible clocking supporting LAN/WAN operation

Telecom Applications

Multi-port XFI/KR to SFI/SFP+ 10 GbE switch cards
10GBASE-KR-compliant backplane transceivers
Networks requiring high-accuracy time synchronization

Telecom Procurement Notes

Verify the specific suffix 'EV' against official Microsemi documentation to confirm if it denotes an evaluation variant or standard production package. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides the original datasheet for final technical validation.

Telecom Selection Notes

Select this component for designs requiring quad-channel 10G/1G connectivity with precise time synchronization. It is suitable for applications needing low power consumption and integrated signal conditioning. Verify compatibility with host interfaces and required management protocols like MDIO before integration.
