Product details
Overview
VSC8564XKS-11 from Microsemi (now Microchip) is a quad-port 10/100/1000BASE-T physical layer transceiver with integrated Synchronous Ethernet timing, Intellisec™ MACsec encryption, and QSGMII/SGMII MAC interface. It supports full-duplex operation across all speeds, delivers <1.5 μs latency per port, and operates at 1.2 V core supply with typical power consumption of 1.8 W in 4×1G mode. It is deployed in carrier-grade Ethernet switches, metro aggregation nodes, and secure industrial backhaul systems.
For engineers reviewing the VSC8564XKS-11 datasheet, VSC8564XKS-11 pinout, VSC8564XKS-11 application, or VSC8564XKS-11 equivalent, key selection criteria include IEEE 802.1AE MACsec support, Synchronous Ethernet (SyncE) clock recovery and distribution, QSGMII/SGMII SerDes compatibility, and compliance with IEEE 802.3ab/802.3u/802.3an standards for copper and fiber media interfacing.
Technical Context
The VSC8564XKS-11 implements four independent PHY channels, each supporting auto-negotiation, parallel detection, and Energy Efficient Ethernet (EEE) per IEEE 802.3az. Its MACsec block performs line-rate encryption/decryption using AES-128-GCM with hardware-accelerated packet classification and replay protection.
Synchronous Ethernet operation is enabled via recovered clock outputs (REFCLK_OUT1/2), configurable jitter attenuation, and ITU-T G.8262 compliance. The device supports automatic media sense, VeriPHY cable diagnostics, and ring resiliency protocols for sub-50 ms failover in metro networks.
Key Specifications

| MDIO/MDC | Serial management interface | IEEE 802.3-compliant two-wire bus for register access, configuration, and status monitoring across all four ports. |
| QSGMII_RX[3:0]/TX[3:0] | Quad-SGMII SerDes lanes | Four differential pairs carrying multiplexed 4×1 Gbps traffic between MAC and PHY; eliminates need for separate SGMII interfaces per port. |
| LED[7:0] | Programmable status indicators | Eight GPIO-mapped LED drivers supporting basic, serial, and enhanced modes for per-port link/speed/activity indication. |
Key Features
| Feature | Design Value |
|---|---|
| Intellisec™ MACsec | Hardware-based AES-128-GCM encryption with zero-latency pipeline, enabling secure Layer 2 transport without CPU offload or software stack dependency. |
| VeriPHY Cable Diagnostics | On-chip time-domain reflectometry (TDR) engine identifies open/short faults and estimates cable length up to 150 m with ±5 m accuracy - eliminates external test equipment during field commissioning. |
| ActiPHY Power Management | Three operational states (low-power, wake-up, normal) reduce idle power by >70% vs. conventional PHYs while maintaining sub-100 ms link reestablishment. |
| Ring Resiliency Support | Hardware-assisted G.8032 ERPS protocol acceleration enables deterministic sub-50 ms network failover - critical for metro Ethernet service-level agreements. |
| Enhanced SerDes Flexibility | Single QSGMII interface supports 4×1 Gbps, while SGMII mode allows 1×1 Gbps per lane; configurable via strap pins or register writes at boot. |

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 | Supports RGMII/SGMII but lacks integrated MACsec and SyncE compliance; uses 1.0 V core supply. | No hardware crypto acceleration; requires external timing IC for G.8262 compliance. | Select when cost sensitivity outweighs security/timing requirements and external crypto/timing ICs are acceptable. |
| Intel Ethernet PHY I210-IT | Single-port 1 GbE PHY with PCIe host interface; no QSGMII, no MACsec, no SyncE. | Designed for PC/embedded host-side NICs, not carrier switch fabric interconnect. | Select only for endpoint NIC applications where quad-port density and telecom timing are irrelevant. |
Compared with the VSC8564XKS-11, the 88E1512 offers lower unit cost but increases system-level BOM and validation effort for secure, timing-critical deployments; the I210-IT serves entirely different architecture roles and cannot substitute in switch fabric or aggregation node designs.

FAQ
What is the primary function of the VSC8564XKS-11 in a network system?
The VSC8564XKS-11 functions as a quad-port 10/100/1000BASE-T physical layer transceiver that bridges MAC-layer devices to copper or fiber media. It integrates Synchronous Ethernet timing recovery, IEEE 802.1AE MACsec encryption, and QSGMII/SGMII SerDes interfaces - enabling secure, low-latency, timing-accurate Ethernet transport in carrier and industrial infrastructure. The VSC8564XKS-11 replaces multiple discrete PHYs and timing/security ICs in a single package.
Does the VSC8564XKS-11 support Energy Efficient Ethernet (EEE)?
Yes, the VSC8564XKS-11 fully supports IEEE 802.3az Energy Efficient Ethernet in both 100BASE-TX and 1000BASE-T modes. It implements low-power idle (LPI) entry/exit with sub-100 μs transition time and maintains full link integrity during LPI states. Power savings are measurable at system level - typical 35% reduction in average power during low-traffic periods. This capability is confirmed in Section 3.5.6 and Table 5.1.9 of the VSC8564XKS-11 datasheet.
Can the VSC8564XKS-11 operate with a single-ended reference clock?
No, the VSC8564XKS-11 requires a differential reference clock input (REFCLK_IN) for stable operation. Section 3.8.2 explicitly specifies LVDS or LVPECL differential signaling; single-ended clock inputs are not supported. Attempting to drive REFCLK_IN with CMOS or TTL signals will result in failed initialization or unstable SerDes lock. The VSC8564XKS-11 must be paired with a differential clock source or buffer, such as Microchip's ZL30252 or equivalent.
What diagnostic capabilities does the VSC8564XKS-11 provide for copper cabling?
The VSC8564XKS-11 includes VeriPHY - an on-die time-domain reflectometry (TDR) engine that detects opens, shorts, and impedance mismatches on Cat5/5e/6 cables. It reports fault distance with ±5 m accuracy up to 150 m and identifies pair skew, split pairs, and reversed polarity. These diagnostics are accessible via MDIO registers (Section 3.19.4) and require no external tools. VeriPHY is active during link training and can be triggered on-demand, making it integral to field deployment and maintenance of the VSC8564XKS-11.
Is the VSC8564XKS-11 pin-compatible with other members of the VSC8564 family?
Yes, the VSC8564XKS-11 shares identical pinout and package with other speed-grade variants in the VSC8564 family (e.g., VSC8564XKS-01, VSC8564XKS-02), differing only in internal configuration fuses and default register settings. All VSC8564XKS-x variants use the same 256-pin FC-BGA footprint and thermal pad layout. However, firmware and strap pin configurations must be validated per variant - the VSC8564XKS-11 is specifically configured for full quad-port 10/100/1000BASE-T operation with SyncE and MACsec enabled at power-on.
