VSC8574XKS-02 - 4-Port Gigabit Ethernet PHY | Microchip
MPN: VSC8574XKS-02 ✓ Hoạt độngVSC8574XKS-02 Tóm tắt
A Gigabit Ethernet physical-layer transceiver converts high-speed serial data into electrical signaling for copper media and optical signaling for fiber media. As a PHY, the VSC8574XKS-02 handles line coding, physical-layer encoding and decoding, clock recovery, link training, and the electrical interface between a network processor or switch ASIC and external transceivers. This four-port device consolidates multiple Ethernet channels into one package while supporting both conventional Gigabit Ethernet and QSGMII aggregation.
Principal features include four Gigabit Ethernet ports, copper and fiber PHY operation, synchronized Ethernet, and IEEE 1588 precision timing through Microchip VeriTime technology. SGMII and QSGMII interfaces connect the PHY to a MAC through a high-speed serial link. Ring Resiliency provides a fault-tolerance mechanism for ring-based network topologies, reducing the operational impact of a broken link or inactive node.
The -02 ordering designation identifies a specific Microchip configuration of the VSC8574 family. Configuration controls, supported features, and operating details should be confirmed against the VSC8574-02 manufacturer datasheet before schematic release. The PBGA-256 package requires a land pattern with dense, fine-pitch routing and careful power-plane integration, making high-layer-count board design, via-in-pad practice, and controlled-impedance layout central to a successful implementation.
Typical deployments include enterprise access switches, telecom access equipment, industrial Ethernet gateways, network appliances, and carrier aggregation systems. Four integrated ports suit designs that need several copper links plus optical uplinks without distributing PHY functions across multiple devices. QSGMII reduces the number of high-speed serial connections to the host MAC when a wider aggregate fabric is required.
For PCB implementation, treat each power rail as a separate distribution problem and place bulk and local decoupling capacitors close to the device supply pins. Keep the QSGMII and SGMII traces short, continuous, and impedance controlled, and avoid routing high-speed serial signals through noisy power or digital return paths. Differential pair geometry, reference-plane continuity, and via transitions should follow the layout guidance in the VSC8574 hardware design checklist.

Ứng dụng tiêu biểu
VSC8574XKS-02 phù hợp cho 6 Áp dụngs: Enterprise Access Switch, Telecom Access and Aggregation Equipment, Industrial Ethernet Gateway, Carrier Aggregation and Ring Networks, Network Appliance with Copper and Fiber Ports, Precision-Time Network Equipment.
Enterprise Access Switch
The VSC8574XKS-02 fits access-layer switches that need four Gigabit Ethernet ports per PHY section and a high-speed host connection. Its QSGMII interface can aggregate four data streams toward a switching ASIC, while SGMII supports designs that require dedicated per-port serial links. This integration reduces the number of PHY devices and board-routing complexity in a 24- or 48-port switch. The four 10/100/1000BASE-T channels also provide copper auto-negotiation while leaving optical uplink expansion to the system architecture. Layout should keep QSGMII traces short, preserve differential impedance, and provide local decoupling at every supply ball.
Được đề xuất
Telecom Access and Aggregation Equipment
The VSC8574XKS-02 is appropriate for carrier access equipment requiring synchronized Ethernet and precise network timing. IEEE 1588 VeriTime support and Synchronous Ethernet are central to transporting time across packet networks, while the four-port copper and fiber PHY arrangement supports service-access line cards with multiple Ethernet endpoints. QSGMII gives the line-card ASIC an efficient aggregate uplink instead of four separate serial interfaces. Ring Resiliency can improve service continuity in ring-based topologies. A production design should validate timing accuracy, thermal performance, and optical-module interoperability under the applicable carrier test plan.
Được đề xuất
Industrial Ethernet Gateway
The VSC8574XKS-02 can serve as the multi-port Ethernet front end of an industrial gateway that connects controllers, sensors, and plant equipment to an upstream network. Four Gigabit Ethernet channels support a mix of machine vision, motion control, and plant-floor Ethernet links in one package, while QSGMII provides a consolidated link to a host processor. Synchronous Ethernet can support time-aware industrial networks where deterministic coordination matters. Ruggedized product designs must still check the device's specified operating temperature and verify conducted-emissions and immunity requirements against the applicable industrial standards.
Được đề xuất
Carrier Aggregation and Ring Networks
Ring Resiliency makes the VSC8574XKS-02 relevant to packet-network designs that use ring topologies for link protection. A broken cable or inactive node in a ring can otherwise interrupt service, whereas a resiliency mechanism helps traffic continue over an alternate path. The device's four-port arrangement fits aggregation shelves where each module terminates several access links and connects them to an upstream port. IEEE 1588 and Synchronous Ethernet complement this role by preserving timing across the packet network. Deployment validation should include failure-injection testing, timing-budget analysis, and recovery-time verification for the complete switching architecture.
Được đề xuất
Network Appliance with Copper and Fiber Ports
The VSC8574XKS-02 suits network appliances that need several copper Ethernet ports plus optical connectivity in a compact board area. Its copper and fiber PHY capability allows a designer to pair the PHY channels with external optical modules for longer-reach uplinks without moving to a separate media-conversion device. Four PHY channels reduce board area relative to four single-port devices, and QSGMII offers a compact host-side connection. Designers must budget board area for optical modules and magnetics, observe fiber-module vendor timing requirements, and place the PHY and high-speed serial interface in a controlled-impedance region of the PCB.
Được đề xuất
Precision-Time Network Equipment
The VSC8574XKS-02 is useful in network equipment that distributes precise time over Ethernet rather than relying on dedicated timing infrastructure. IEEE 1588 support and Synchronous Ethernet allow the PHY to participate in timing-aware packet transport, while four ports provide multiple physical links for aggregation and redundancy. This combination is relevant to test systems, synchronization infrastructure, and industrial controllers requiring a common time reference. A successful implementation requires correct reference-clock architecture, disciplined timing configuration, and validation of jitter and wander budgets through the complete switching and cabling path.

Ghi chú thiết kế
Place bulk and local decoupling capacitors immediately adjacent to the appropriate PBGA supply balls. The VSC8574 hardware design checklist recommends minimizing resistive supply drop and using correctly positioned local decoupling for each supply. Maintain continuous reference planes beneath the device and avoid splitting planes beneath high-speed signal routing. Validate the final stack-up, via geometry, and power-plane current density before fabrication.
Route SGMII and QSGMII links as controlled-impedance differential pairs with short, continuous reference paths and minimal stub vias. Avoid crossing noisy digital return paths and keep clock-distribution lines isolated from high-speed data where possible. Use the manufacturer timing and layout guidance for pair spacing, via transitions, and connector or ASIC escape routing. Post-layout signal-integrity simulation is recommended for long QSGMII reaches.
Do not treat a family member with the same package as an automatic substitute. Before replacing the VSC8574XKS-02, verify supply rails, exposed-ball assignments, serial-interface configuration, IEEE 1588 support, Synchronous Ethernet, Ring Resiliency, reference-clock requirements, and register behavior. Also confirm the ordering-code temperature and packaging requirements. A footprint match alone does not guarantee an interoperable replacement.
The four integrated copper PHYs can create a significant high-frequency switching environment on the board. Keep magnetics, optical modules, and external connectors away from sensitive clock and reference-distribution paths, and provide solid grounding around interface connectors. Use the hardware design checklist when selecting ferrite beads or inductors for supply filtering, and validate radiated and conducted emissions with the final enclosure and cable configuration.
Estimate total board-level heat rise from the PHY power, adjacent regulators, magnetics, and optical modules rather than the PHY alone. The PBGA-256 package has many fine-pitch balls that can complicate solder inspection and rework, so assembly process control is important. Use the manufacturer thermal information to select via-in-pad or filled thermal-via structures where supported, and validate junction margin at the highest expected ambient temperature.
