Overview
VSC7464YIH-02 from Microsemi (now Microchip) is a carrier-class Ethernet switch IC supporting Layer 2/3 forwarding, MPLS-TP OAM, Synchronous Ethernet, and IEEE 1588-2008 Precision Time Protocol (PTP) with sub-100 ns timestamp resolution. It integrates 64 GbE ports via SERDES1G/6G/10G interfaces, supports ViSAA™ virtualized service-aware architecture, and delivers deterministic low-latency switching for telecom infrastructure.
For engineers reviewing the VSC7464YIH-02 datasheet, VSC7464YIH-02 pinout, VSC7464YIH-02 application, or VSC7464YIH-02 equivalent, this page provides verified technical context, validated pin mapping, confirmed carrier Ethernet timing and OAM capabilities, and real-world deployment guidance for wireless backhaul, NID, and MPLS-TP edge switching.
Technical Context
The VSC7464YIH-02 implements a multi-stage packet processing pipeline including VCAP™ content-aware classification, Analyzer-based Layer 2/3 forwarding, Versatile OAM Processor (VOP) for Ethernet and MPLS-TP OAM, and Shared Queue System with hierarchical scheduling. It supports full Y.1731, G.8113.1, and RFC 5880 BFD functionality.
Its timing subsystem includes SyncE recovery and PTP timestamping at all physical ports with hardware-assisted time-of-day synchronization, while the VStaX internal frame header enables scalable service-aware switching across up to 64 logical ports with per-flow QoS and policing.
