VSC8486YSN-04

Overview

The VSC8486YSN-04 is a single-channel 10 Gbps XAUI or XGMII to XFI LAN/WAN transceiver manufactured by Microchip Technology. It supports both XAUI and XGMII input interfaces, converting them to an XFI output interface compliant with IEEE 802.3ae standards. The device integrates a Physical Media Attachment (PMA), WAN Interface Sublayer (WIS), Physical Coding Sublayer (PCS), and Extended PCS (E-PCS). It features comprehensive loopback capabilities for testing, including deep network, shallow system, and PHY XS loopbacks. The component includes support for Synchronous Ethernet in conventional and enhanced modes, as well as autonegotiation via the E-PCS. It operates within a temperature range of -40°C to +85°C and utilizes a BGA package.
