VSC8484KITEV

Overview

The VSC8484KITEV is a quad-channel Ethernet transceiver designed for WAN, LAN, and backplane applications. It converts XAUI signals to SFP+, KR, or SFI interfaces at data rates up to 10 Gb/s per channel. The device supports rate auto-negotiation and includes integrated clock and data recovery (CDR) with variable gain amplifiers. It features a 64B/66B Physical Coding Sublayer (PCS), Forward Error Correction (FEC), and a WAN Interface Sublayer (WIS). Management is handled via MDIO, JTAG, and UART interfaces.

Feature Summary

• Supports conversion between XAUI client interfaces and SFP+, 10GBASE-KR, or SFI physical media attachments.
• Integrates a 64B/66B Physical Coding Sublayer (PCS) with built-in BIST capabilities.
• Includes a full WAN Interface Sublayer (WIS) for SONET/SDH overhead processing.
• Features integrated Clock and Data Recovery (CDR) with equalization for signal integrity.

Applications

• WAN aggregation and transport equipment
• LAN switches and routers requiring high-density ports
• Backplane interconnects in telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'KIT' against official Microchip documentation to confirm if it denotes a kit configuration or specific package variant. Ensure compatibility with existing firmware loads and power supply requirements before procurement.

Selection Notes

Select this component when a quad-channel solution is required for XAUI to SFP+/KR/SFI conversion. Verify that the system design accommodates the necessary reference clocks and power domains specified in the datasheet electrical characteristics.

Part Context
