VSC8564XKS-14 4-Port GbE PHY | Microchip Technology
料号： VSC8564XKS-14 ✓ 量产中VSC8564XKS-14 概述
An Ethernet interface IC is a semiconductor that connects an embedded system or communications processor to physical Ethernet networks. This device belongs to the Gigabit Ethernet controller and Ethernet transceiver hierarchy, combining physical-layer signaling, QSGMII-based port expansion, and MACsec support. Its 256-PBGA package provides a high pin count for four-port networking designs, power delivery, reference-clock connections, and high-speed serial interfaces.
Key features include four Gigabit Ethernet ports, support for copper and fiber PHYs, QSGMII connectivity, and MACsec hardware acceleration. The industrial-temperature designation makes the device suitable for equipment expected to operate outside consumer-only temperature environments. Its 256-pin, 17 mm by 17 mm PBGA package is designed for multilayer PCB layouts, controlled impedance routing, and proper power and ground distribution beneath a dense component.
The VSC8564 family uses a high-speed serial architecture to connect multiple Ethernet channels to a host processor or network controller. QSGMII provides a four-lane serial interface for parallel port aggregation, while MACsec support provides hardware assistance for protecting Ethernet traffic at line rate. Exact lane rates, protocol options, clock requirements, register details, and electrical characteristics should be confirmed in the manufacturer datasheet before schematic capture.
Typical uses include industrial Ethernet switches, telecom access equipment, network appliances, fiber-to-copper media systems, and secure industrial gateways. In a four-port switch design, the device can provide PHY connectivity for multiple copper or fiber links while a host processor handles higher-layer switching and management functions. MACsec support is useful when equipment requires hardware-assisted link-layer encryption.
PCB implementation requires careful attention to high-speed signal integrity, layer transitions, via symmetry, reference planes, and power delivery. Follow the Microchip layout guidance for the 256-PBGA footprint, preserve continuous ground references beneath the device, and use the recommended decoupling network at each supply input. Confirm all AC coupling, terminations, and clock connections against the applicable hardware design guidance.
This page combines the exact product identity, source links, application engineering guidance, and verified drop-in compatibility information. Because detailed electrical tables and a public numbered pin list were not established, the unknown values are marked explicitly rather than inferred.

典型应用
VSC8564XKS-14 适用于 6 应用s: Industrial Ethernet Switching, Telecom Access Equipment, Fiber-to-Copper Media Systems, Secure Network Appliances, Industrial IoT Gateways, Network Timing Equipment.
Industrial Ethernet Switching
The VSC8564XKS-14 fits a four-port managed-switch design because it combines four Gigabit Ethernet PHY channels with QSGMII connectivity to a switching host. Its industrial-temperature designation supports deployments in factory equipment, control cabinets, and industrial gateways where commercial-temperature components may be unsuitable. Copper and fiber PHY support lets one platform address both electrical and optical links. MACsec hardware support can protect traffic without relying entirely on software encryption, although the final system design must verify protocol configuration, clocking, thermal margins, and all electrical limits against the Microchip documentation.
推荐
Telecom Access Equipment
For telecom access and aggregation equipment, the VSC8564XKS-14 can supply four Gigabit Ethernet physical-layer connections while QSGMII links those ports to a host processor. Its MACsec capability is relevant to infrastructure requiring link-layer traffic protection, and the 256-pin PBGA provides the interface density needed for a high-speed multilayer board. Designers should reserve controlled-impedance routing for QSGMII, maintain uninterrupted reference planes, place decoupling close to supply pins, and verify operating-temperature and protocol requirements before release.
推荐
Fiber-to-Copper Media Systems
The VSC8564XKS-14 is appropriate for media-conversion systems because its four-port architecture supports copper and fiber PHY options. A network appliance can use some ports for external copper links and others for optical backhaul, reducing the number of separate interface devices required on the board. The QSGMII host connection provides a scalable path for port management, while MACsec can secure traffic between network segments. Optical magnetics, line-amplitude settings, channel separation, and thermal performance must be validated with the complete reference design.
推荐
Secure Network Appliances
A secure gateway or firewall can use the VSC8564XKS-14 for four Gigabit Ethernet connections and MACsec-assisted traffic protection. This arrangement offloads supported link-layer cryptographic functions while leaving policy control and higher-layer processing to the system processor. The industrial-temperature grade suits network equipment deployed in controlled industrial spaces, while the 256-PBGA package supports compact multilayer designs. Validate cryptographic mode support, key-management assumptions, thermal performance, and interface timing against the manufacturer documentation before deploying the device in a security boundary.
推荐
Industrial IoT Gateways
The four Gigabit Ethernet ports make the VSC8564XKS-14 useful in industrial IoT gateways that aggregate machine, sensor, and plant-network traffic. Copper links can connect field equipment while fiber ports extend connectivity through electrically noisy or geographically distributed installations. MACsec support can protect selected links, and QSGMII allows the ports to connect efficiently to an embedded host. A robust design should include ESD and surge protection, isolated boundary planning where required, thermal analysis, careful BGA layout, and validation of every supported PHY configuration.
推荐
Network Timing Equipment
The VSC8564XKS-14 can serve in networking equipment that requires Ethernet connectivity without making PTP timing its primary function. When precise 1588v2 synchronization is unnecessary, the VSC8564 provides the four-port Gigabit Ethernet interface and MACsec support in the same package family. For designs requiring PTP, Microchip identifies the VSC8584 as a pin-compatible option. Timing-sensitive engineers should compare clock architecture, timestamp behavior, synchronization requirements, and thermal conditions before choosing between these devices, while preserving the common 256-PBGA PCB approach.

设计说明
Route QSGMII as a controlled-impedance high-speed interface with a continuous reference plane and no plane splits beneath the signal path. Follow the Microchip 256-PBGA land pattern and guidance for layer transitions, via construction, and breakout geometry. Keep the escape routing compact, maintain consistent topology between lanes, and review the complete stack-up because package breakout and interlayer via transitions can materially affect signal integrity.
Use the power architecture, decoupling values, and supply sequencing shown in the Microchip hardware design guidance. Place each decoupling capacitor close to its associated supply and ground pins, provide a low-impedance ground reference beneath the BGA, and minimize shared copper resistance between power and ground connections. Validate the network with appropriate power-integrity analysis and verify the final design across voltage, temperature, and transient conditions.
Do not estimate the 256-PBGA thermal margin from package size alone. Build the thermal path through top and bottom copper, board vias, and the enclosure, then apply the manufacturer power data for the selected operating mode. Review adjacent heat sources and the worst-case ambient temperature. For industrial systems, confirm that the operating point and enclosure temperature remain inside the device's qualified limits.
Do not infer the VSC8564XKS-14 ball assignments or power configuration from a generic 256-BGA drawing. Use the exact Microchip pin-description table and land pattern, including exposed-pad or thermal-array requirements. Also verify the selected PHY mode, reference-clock source, MACsec configuration, and reset or sequencing behavior. A mechanically similar BGA package does not guarantee electrical or protocol compatibility.
