Product details
Overview
VSC8582XKS-10 from Microsemi (now Microchip) is a dual-port 10/100/1000BASE-T Ethernet PHY IC with integrated IEEE 1588v2 precision time stamping, MACsec encryption, Synchronous Ethernet, VeriTime™ cable diagnostics, and QSGMII/SGMII MAC interface. It supports full-duplex operation across all speeds, delivers ±50 ppb frequency accuracy under SyncE, and enables deterministic timing in carrier-grade Ethernet switches and packet transport networks.
For engineers reviewing the VSC8582XKS-10 datasheet, VSC8582XKS-10 pinout, VSC8582XKS-10 application, or VSC8582XKS-10 equivalent, key selection criteria include IEEE 1588 one-step E2E transparent clock support, hardware-accelerated MACsec AES-128, dual-port daisy-chainable time stamping, and compliance with ITU-T G.8261/G.8262 SyncE standards - critical for mobile fronthaul, industrial TSN, and metro aggregation systems.
Technical Context
The VSC8582XKS-10 implements a dual-channel SerDes architecture supporting simultaneous QSGMII/SGMII-to-1000BASE-X and QSGMII/SGMII-to-100BASE-FX media conversion, with independent IEEE 1588 timestamping engines per port. Its MACsec block operates inline at line rate with zero latency impact on encrypted frames.
It integrates ActiPHY power management for sub-100 mW low-power link-down states, supports ring resiliency via proprietary failover protocols, and provides differential REFCLK input (25/125 MHz) with programmable offset for LTC load register alignment to external PTP grandmasters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell Alaska 88E1512 | Lacks integrated IEEE 1588v2 timestamping engine; requires external PTP hardware assist; no MACsec acceleration. | Suitable for cost-sensitive enterprise switches where precise timing is not required. | Select when SyncE and MACsec are not mandated, and system-level PTP is handled by host CPU or FPGA. |
| Intel Ethernet PHY I210-AT | Single-port only; no QSGMII interface; limited to PCIe-hosted embedded applications; no VeriPHY diagnostics. | Targeted at x86-based industrial PCs and embedded controllers with direct CPU integration. | Choose for PC-based edge gateways needing basic 10/100/1000BASE-T with minimal footprint, not carrier-grade timing/security. |
Compared with Marvell 88E1512 and Intel I210-AT, the VSC8582XKS-10 uniquely combines dual-port 1588v2 timestamping, hardware MACsec, and VeriPHY diagnostics in a single LFBGA package - enabling compact, secure, and timing-accurate carrier-class line cards without external timing or security co-processors.

FAQ
What is the primary function of the VSC8582XKS-10 in a network system?
The VSC8582XKS-10 serves as a dual-port Ethernet physical layer transceiver that bridges MAC-layer interfaces (QSGMII/SGMII) to copper or fiber media (1000BASE-T/X, 100BASE-FX). Its core functions include IEEE 1588v2 hardware timestamping, MACsec AES-128 encryption, Synchronous Ethernet clock recovery, and VeriPHY cable diagnostics - making it essential for timing-critical and security-sensitive carrier and industrial networks. The VSC8582XKS-10 enables deterministic packet processing without host CPU involvement.
Does the VSC8582XKS-10 support IEEE 1588v2 one-step transparent clock operation?
Yes, the VSC8582XKS-10 fully supports IEEE 1588v2 one-step end-to-end transparent clock (E2E TC) operation with hardware-accelerated timestamp insertion and correction. It calculates and updates frame residence time in real time, modifies the correctionField in PTP messages, and maintains ±50 ns timestamp resolution - all without software intervention. This capability is integral to the VSC8582XKS-10's role in mobile fronthaul and metro aggregation where sub-microsecond timing accuracy is mandatory.
How does the VSC8582XKS-10 implement MACsec encryption?
The VSC8582XKS-10 integrates Intellisec™, a dedicated hardware MACsec engine compliant with IEEE 802.1AE-2018. It performs AES-128-GCM encryption and decryption inline at full 1 Gbps line rate per port, with zero added latency or jitter. Keys are loaded via MDIO or SPI, and secure channels are established without CPU offload. This design ensures the VSC8582XKS-10 meets carrier-grade security SLAs while eliminating bottlenecks associated with software-based MACsec implementations.
What package type and pin count does the VSC8582XKS-10 use?
The VSC8582XKS-10 uses a 256-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) package measuring 17 mm × 17 mm × 1.4 mm with 0.8 mm ball pitch. This package supports high-speed signal routing, thermal dissipation in dense line cards, and compatibility with standard telecom PCB assembly processes. Pin assignments include dedicated differential REFCLK inputs, QSGMII/SGMII SerDes lanes, 1000BASE-T analog front-end pairs, and configurable LED/GPIO terminals - all validated in the official Microsemi datasheet VMDS-10421 Rev 4.3.
Can the VSC8582XKS-10 operate with both copper and fiber media simultaneously?
Yes, the VSC8582XKS-10 supports concurrent copper and fiber operation through its flexible SerDes media interface: one port can be configured for 1000BASE-T over Cat5e/6 while the other operates as 1000BASE-X over fiber (or 100BASE-FX), using QSGMII/SGMII-to-media protocol conversion. This dual-mode capability is enabled by independent SerDes channel configuration registers and verified in functional description Section 3.3 of the VSC8582XKS-10 datasheet. The VSC8582XKS-10 thus enables hybrid access architectures without external media converters.
