Product details
Overview
VSC8564XKS-14 from Microsemi (now Microchip) is a quad-port 10/100/1000BASE-T Ethernet PHY IC with integrated Synchronous Ethernet timing, Intellisec™ MACsec encryption, and QSGMII/SGMII MAC interface. It supports full-duplex operation across all speeds, delivers ≤1.2 W typical power consumption in active mode, and enables carrier-grade resiliency via Ring Resiliency and Fast Link Failure Indication - deployed in metro edge routers and industrial Ethernet switches.
For engineers reviewing the VSC8564XKS-14 datasheet, VSC8564XKS-14 pinout, VSC8564XKS-14 application, or VSC8564XKS-14 equivalent, key selection criteria include IEEE 802.1AE MACsec support, synchronous Ethernet (SyncE) clock recovery accuracy of ±50 ppb, QSGMII SerDes bandwidth up to 4×1.25 Gbps, and compliance with IEEE 802.3ab/802.3u/802.3z/802.3ae standards.
Technical Context
The VSC8564XKS-14 implements four independent PHY lanes with dual-mode SerDes supporting both QSGMII (4-lane 1.25 Gbps aggregate) and SGMII (single-lane 1.25 Gbps) MAC interfaces. Its MACsec block operates inline at line rate with AES-128-GCM encryption and per-packet authentication, while the SyncE engine recovers and generates traceable clocks compliant with ITU-T G.8262 EEC Option 2.
It integrates VeriPHY cable diagnostics, ActiPHY low-power states (≤15 mW in sleep), and IEEE 802.3az Energy Efficient Ethernet. The device uses a 100-pin TQFP package with dedicated REFCLK_IN, MDIO/MDC, and GPIO pins for system-level control and monitoring.

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 | Single-port 10/100/1000BASE-T PHY; requires four units for quad configuration; no integrated MACsec or SyncE | Lacks hardware MACsec and telecom-grade timing - needs external crypto and clock ICs for equivalent functionality | Select when cost-per-port is prioritized over integration and security; verify PCB layout supports four separate PHYs and associated support circuitry |
| Microchip LAN8814 | Dual-port 10/100/1000BASE-T PHY with IEEE 1588v2 timestamping and basic EEE; no QSGMII or MACsec | Targeted at industrial IoT gateways - missing carrier-grade features like Ring Resiliency and SyncE EEC Option 2 | Choose for time-sensitive networking (TSN) edge nodes where PTP precision matters more than encryption or ring redundancy |
Compared with the VSC8564XKS-14, the 88E1512 increases board area and component count due to discrete implementation, while the LAN8814 omits critical carrier infrastructure capabilities - making the VSC8564XKS-14 the only single-package solution delivering quad-port PHY, MACsec, and SyncE in one IC.

FAQ
What is the primary function of the VSC8564XKS-14 in an Ethernet system?
The VSC8564XKS-14 serves as a quad-port 10/100/1000BASE-T physical layer transceiver that bridges copper media to QSGMII/SGMII MAC interfaces. It performs signal conditioning, autonegotiation, clock recovery, and line-rate MACsec encryption - enabling secure, timing-accurate, and resilient Gigabit Ethernet connectivity in carrier and industrial systems. The VSC8564XKS-14 integrates functions traditionally requiring multiple discrete ICs.
Does the VSC8564XKS-14 support IEEE 1588 Precision Time Protocol (PTP)?
Yes, the VSC8564XKS-14 supports IEEE 1588v2 as a PTP slave through its Synchronous Ethernet engine and recovered clock outputs. It provides hardware timestamping capability via the MAC SerDes interface and enables sub-microsecond time alignment when paired with a PTP-aware MAC. The VSC8564XKS-14 does not implement full PTP master functionality but delivers the precise clock recovery essential for slave operation.
Can the VSC8564XKS-14 operate without an external crystal or oscillator?
No - the VSC8564XKS-14 requires an external 25 MHz or 125 MHz differential reference clock applied to REFCLK_IN for SerDes PLL locking and internal timing generation. It does not contain an integrated oscillator or crystal driver. The VSC8564XKS-14 relies on this externally supplied clock for all high-speed SerDes and MAC interface operations.
What diagnostic capabilities does the VSC8564XKS-14 provide for copper cabling?
The VSC8564XKS-14 includes VeriPHY - an on-chip time-domain reflectometry (TDR) engine that measures cable length (up to 150 m), detects opens/shorts, identifies impedance mismatches, and reports pair skew. Results are accessible via MDIO registers and require no external test equipment. This diagnostic capability is built into the VSC8564XKS-14 and operates independently per port during link initialization or on-demand.
Is the VSC8564XKS-14 pin-compatible with other members of the VSC8564 family?
Yes - the VSC8564XKS-14 shares identical 100-pin TQFP packaging and pinout with other VSC8564 variants including VSC8564XKS-01 and VSC8564XKS-11. Differences between variants relate to firmware configuration, default strap settings, and qualification grade (e.g., industrial vs. extended temp), not physical layout. System-level compatibility is maintained across the VSC8564XKS-14 family.
