VSC7398XYU - 8-Port Gigabit Ethernet Switch | Microchip
Teilenummer: VSC7398XYU ✗ AbgekündigtVSC7398XYU Übersicht
An Ethernet switch is a networking semiconductor that connects multiple Ethernet endpoints through a shared switching fabric. It inspects incoming Ethernet frames and forwards traffic toward the appropriate destination port, while also handling other Layer 2 functions implemented by the device. The VSC7398XYU sits in the hierarchy of Ethernet interface integrated circuits, network switches, interface ICs, semiconductors, and embedded networking equipment. Integrating the switch function and physical-layer transceivers into one device simplifies hardware design in gateways, industrial controllers, access equipment, and embedded network systems.
The principal verified features are the eight integrated Gigabit Ethernet ports, support for 10, 100, and 1000 Mbps operation, nonblocking wire-speed performance, and IEEE 802.3ab-compliant copper transceivers. All eight ports support copper connectivity through integrated PHYs. This integration reduces the number of separate network interface devices required when several Ethernet connections must terminate on one circuit board. The exact switching fabric throughput, latency, SRAM organization, voltage ratings, and management-interface details are not included in the supplied verified data and therefore require confirmation from the manufacturer datasheet.
The SparX-G8e implementation consolidates switching and transceiver functions within a single highly integrated mixed-signal network IC. This architecture is appropriate for equipment requiring multiple Ethernet ports but limited board space, such as compact access points, industrial communication controllers, and embedded gateways. Because the copper PHYs are integrated, board-level design must account for the device's thermal behavior, high-speed differential routing, magnetics or coupling requirements, controlled impedance, and layout practices specified by Microchip. The supplied data does not provide the complete reference design or pin-level electrical constraints, so those details should be obtained from the official documentation before schematic capture.
Typical applications include eight-port industrial Ethernet switching, embedded control and test systems, telecom access equipment, industrial automation gateways, network appliances, and compact embedded communication platforms. The eight-port configuration is particularly useful when a system must connect controllers, sensors, service equipment, and supervisory computers through isolated Ethernet interfaces. Using a nonblocking, wire-speed switch allows traffic to be aggregated while avoiding the component count of eight standalone Ethernet interface devices.
Designers should obtain the official VSC7398 product brief, datasheet, CAD models, and reference schematic before committing the 757-BGA footprint. The supplied distributor information identifies the package as 757-BGA (40x40), but no verified pinout, power-supply values, maximum copper-cable length, operating-temperature range, or recommended magnetics data were provided. Those parameters must be verified rather than inferred because the Ethernet PHYs, supply rails, clocking, and high-speed copper interfaces determine whether a particular board design will meet system requirements.
This page consolidates the verified manufacturer and distributor findings for the VSC7398XYU, explicitly distinguishes confirmed specifications from missing data, and records the product's NRND status. It also provides engineering-focused application guidance and a source-traceable comparison framework. No unsupported drop-in alternatives, package substitutions, pricing values, pin assignments, or unverified performance claims are presented.

Typische Anwendungen
VSC7398XYU ist geeignet für 6 Anwendungs: Industrial Ethernet Control Gateway, Telecom Access Equipment, Embedded Network Appliance, Network Test and Measurement, Industrial Automation Controller, Multiport Network Service Adapter.
Industrial Ethernet Control Gateway
The VSC7398XYU fits an industrial Ethernet gateway that must consolidate multiple machine and sensor connections before forwarding data to a controller or supervisory system. Its eight integrated 10/100/1000 Mbps copper PHYs avoid eight separate external PHY packages, while the SparX-G8e switch architecture provides nonblocking wire-speed operation. The design should follow Microchip's reference layout for the 757-BGA device, including controlled-impedance differential routing and verified magnetics or coupling components. Supply voltages, clock requirements, thermal limits, and industrial temperature qualifications were not included in the supplied data and must be confirmed before deployment.
Empfohlen
Telecom Access Equipment
The VSC7398XYU is suitable for compact telecom access equipment requiring eight local Ethernet service ports with integrated physical layers. Each copper interface supports 10, 100, and 1000 Mbps, allowing equipment to accommodate management, service, and uplink connections through one switching IC. The SparX-G8e architecture supplies nonblocking wire-speed switching across the eight-port configuration. Because this part is marked Not Recommended for new designs, an access-equipment program should evaluate lifecycle risk carefully and obtain current availability, traceability, and long-term support commitments from Microchip.
Empfohlen
Embedded Network Appliance
The VSC7398XYU can consolidate eight wired Ethernet connections in an embedded appliance such as a protocol gateway, test controller, or communications concentrator. Its integrated tri-speed PHYs permit links to operate from 10 Mbps legacy equipment through 1000 Mbps backbone connections, while nonblocking wire-speed switching supports simultaneous traffic handling. Integration reduces board area and component count compared with eight discrete network interfaces. PCB implementation still requires careful separation of supply and ground planes, high-speed differential routing, verified magnetics selection, and thermal analysis based on the complete switching load and copper-port activity.
Empfohlen
Network Test and Measurement
The VSC7398XYU is a reasonable switching element for compact test and measurement systems that must present several Ethernet-controlled instruments or service interfaces. Eight integrated Gigabit copper ports can replace multiple standalone Ethernet interface circuits and support nonblocking wire-speed traffic across connected endpoints. In such systems, firmware configuration, port diagnostics, and management access remain important considerations and should be verified from the complete VSC7398 documentation. The supplied record does not include maximum frame size, latency, temperature range, or power dissipation, so these values must be checked before fixing test-system timing and thermal margins.
Empfohlen
Industrial Automation Controller
The VSC7398XYU can serve as the central eight-port Ethernet interface in a programmable automation controller, connecting remote I/O modules, drives, vision systems, and supervisory HMIs. Tri-speed support allows each attached device to negotiate at 10, 100, or 1000 Mbps, and integrated PHYs streamline board design in space-constrained controllers. Nonblocking wire-speed switching is beneficial when several devices exchange traffic concurrently. Designers must still validate real-time traffic behavior, supported frame sizes, recovery features, operating-temperature limits, and industrial compliance; those details were not available in the supplied verified dataset.
Empfohlen
Multiport Network Service Adapter
The VSC7398XYU is appropriate for a service adapter or edge node that must present eight copper Ethernet interfaces to legacy and modern network equipment. Because all eight ports include tri-speed PHYs, one device supports heterogeneous links operating at 10, 100, or 1000 Mbps rather than requiring separate copper-interface devices for each rate. The nonblocking SparX-G8e switching architecture supports simultaneous traffic at wire speed. Production implementation should follow the manufacturer's 757-BGA land pattern and reference schematic, confirm available power rails, and validate magnetics, connector layout, thermal performance, and unmanaged port-management assumptions before release.

Designhinweise
Implement the VSC7398XYU PCB using the official 757-BGA CAD models and reference layout rather than a generic BGA land pattern. The eight copper PHYs require controlled-impedance differential routing, short return paths, continuous reference planes, and manufacturer-approved connector or magnetics layouts. Keep switching and PHY supply distribution networks isolated according to the official decoupling guidance, and verify the exposed-package thermal interface before production release.
Determine the required core and Ethernet-PHY supply rails from the official VSC7398 datasheet before power-supply design; these values were not present in the supplied verified data. Estimate dissipation from the actual input voltages, total switching activity, and PHY loading, then add margin for worst-case ambient temperature. Avoid assuming that a generic Ethernet-switch regulator is adequate, because sequencing, noise sensitivity, and the relationship between logic and PHY supplies are device-specific.
Route each copper Ethernet differential pair as a controlled-impedance pair with minimal length mismatch, avoid stubs, and maintain uninterrupted reference planes beneath the pair. Separate high-current switching and supply-return paths from sensitive clock or management signals where the reference design permits. Connector, magnetics, and PHY placement should follow Microchip's validated example to minimize insertion loss, skew, reflections, and radiated emissions.
Do not treat the VSC7398XYU as a generic eight-port Ethernet switch when evaluating a replacement. Pin compatibility must account for all 757 BGA balls, supply rails, clocks, management signals, PHY copper interfaces, and board-level programming requirements. In addition, the product family is NRND, so obsolete-part substitution without written lifecycle and traceability review can create long-term sourcing and qualification risks.
Compliance-Informationen
The supplied VSC7398 data identifies the part as RoHS compliant and lead free. REACH, halogen-free, conflict-minerals, and automotive-qualification details were not supplied; AEC-Q100 is marked not_applicable because this integrated Ethernet switch was not identified as an automotive-qualified product.
