Product details
Overview
VSC8584XKS-14 from Microsemi (now Microchip) is a quad-port 10/100/1000BASE-T Ethernet PHY IC with integrated IEEE 1588v2 precision timing, MACsec encryption, Synchronous Ethernet, VeriTime™ time-stamping, and QSGMII/SGMII MAC interface. It supports full-duplex operation across all speeds, delivers sub-50 ns timestamp resolution, and operates in industrial temperature range (–40°C to +85°C) in a 324-pin FC-BGA package.
For engineers reviewing the VSC8584XKS-14 datasheet, VSC8584XKS-14 pinout, VSC8584XKS-14 application, or VSC8584XKS-14 equivalent, key selection criteria include IEEE 1588 one-step E2E transparent clock support, hardware-accelerated MACsec AES-128, dual-reference clock inputs (25/125 MHz), and integrated ring resiliency for carrier-grade Ethernet switches and time-aware industrial controllers.
Technical Context
The VSC8584XKS-14 implements four independent PHY lanes with full 10/100/1000BASE-T transceivers, each supporting autonegotiation, Energy Efficient Ethernet (EEE), and VeriPHY cable diagnostics. Its SerDes layer handles QSGMII/SGMII-to-1000BASE-X and QSGMII/SGMII-to-100BASE-FX media conversion with configurable protocol transfer modes.
IEEE 1588v2 functionality is implemented via dedicated hardware blocks including a local time counter (LTC), serial time stamp output interface, pulse-per-second (PPS) generator, and Y.1731 one-way/two-way delay measurement support. The MACsec engine operates inline at line rate with zero latency impact and supports secure channel establishment per port.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-port Gigabit Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell Alaska 88E1512 | Lacks IEEE 1588 hardware timestamping, no MACsec engine, supports only SGMII (not QSGMII), no ring resiliency. | Suitable for cost-sensitive enterprise switches without timing/security requirements. | Select only if IEEE 1588, MACsec, or ERPS are not required - avoids over-specification and reduces licensing overhead. |
| Intel Ethernet PHY I210-IT | Single-port device; no QSGMII; limited 1588 support (software-assisted only); no hardware MACsec; industrial temp rated. | Targeted at embedded x86 platforms needing basic 1 GbE with ruggedized operation. | Use when integrating into Intel-based control systems with minimal timing demands and no multi-port aggregation needs. |
Compared with Marvell 88E1512 and Intel I210-IT, the VSC8584XKS-14 uniquely integrates carrier-grade timing, security, and resiliency in a single quad-port device - eliminating interposer logic, reducing PCB layers, and enabling unified firmware management for time-critical infrastructure.

FAQ
What is the primary function of the VSC8584XKS-14 in an Ethernet system?
The VSC8584XKS-14 serves as a quad-port 10/100/1000BASE-T physical layer transceiver that bridges MAC-layer interfaces (QSGMII/SGMII) to copper or fiber media. It provides full PHY functions including autonegotiation, EEE, VeriPHY diagnostics, and - critically - hardware-accelerated IEEE 1588v2 timestamping and MACsec encryption. In systems like metro switches or TSN controllers, the VSC8584XKS-14 ensures deterministic latency, secure data transport, and precise time distribution without CPU offload.
Does the VSC8584XKS-14 support IEEE 1588v2 in hardware or software?
The VSC8584XKS-14 implements IEEE 1588v2 entirely in hardware, including a dedicated local time counter (LTC), serial time stamp output interface, PPS generator, and Y.1731 delay measurement blocks. Timestamp capture occurs at the physical layer with sub-50 ns resolution, independent of host processor load. This hardware implementation enables one-step end-to-end transparent clock operation and meets ITU-T G.8265.1 accuracy requirements - a capability not found in software-timestamped alternatives like the Intel I210-IT.
Can the VSC8584XKS-14 operate with different reference clock frequencies per port group?
Yes. The VSC8584XKS-14 accepts two independent reference clocks: REFCLK_IN[0] (25 MHz) for ports 0 and 1, and REFCLK_IN[1] (125 MHz) for ports 2 and 3. This dual-clock architecture allows mixed-media deployments - for example, connecting 100BASE-TX uplinks (25 MHz domain) and 1000BASE-T downlinks (125 MHz domain) simultaneously without clock domain crossing logic. The VSC8584XKS-14 internally synchronizes timestamp operations across both domains using its LTC and 1588_DIFF_INPUT_CLK configuration registers.
How does MACsec integration work in the VSC8584XKS-14?
The VSC8584XKS-14 embeds Microsemi's Intellisec™ MACsec engine, which performs AES-128 encryption/decryption inline at full 1 Gbps per port with zero added latency. It supports secure association (SA) setup via MKA (MACsec Key Agreement), replay protection, and hardware-managed SA rollover. Unlike external crypto ICs, the VSC8584XKS-14 processes MACsec frames before serialization - ensuring frame integrity is verified prior to transmission and preventing malformed packets from entering the network. This is confirmed in Section 3.6 of the VMDS-10455 datasheet.
Is the VSC8584XKS-14 pin-compatible with other members of the VSC8584 family?
Yes - the VSC8584XKS-14 shares identical 324-pin FC-BGA mechanical footprint and core pinout with VSC8584XKS-01, -02, and -11 variants. Differences are limited to internal configuration fuses and default strap settings (e.g., PHY address, default clock mode). All variants use the same register map, SMI interface, and timing architecture. This allows drop-in replacement during design iteration or qualification - provided the target application aligns with the specific feature set enabled in each variant's mask ROM.
