VSC7460YIH - 24x1G + 4x10G XAUI Ethernet Switch | Microchip
MPN： VSC7460YIH ✓ 啟用中VSC7460YIH 概覽
An Ethernet switch is an integrated circuit that frames and forwards Ethernet packets between multiple ports using dedicated hardware rather than a host processor. It sits below the network processor in the equipment hierarchy and above the physical PHY layer. The VSC7460YIH is a Carrier Ethernet (CE) switch, meaning it adds telecom-oriented functions such as service and port policing, traffic classification, and sub-50 ms protection switching to a conventional enterprise switch core.
Key features of the device include 24 copper Gigabit Ethernet ports for 1000BASE-T, 100BASE-TX and 10BASE-T links, four XAUI lanes running at 10 Gbps each for high-speed uplink or stacking connections, and optional support for up to eight 2.5 Gbps Ethernet ports when two of the XAUI lanes are reconfigured. The part is supplied in a 672-pin square CGA-code HFCBGA package and is listed as lead-free (Pb free) with an automotive temperature grade designation.
Architecturally, the switch is built around a high-performance packet-processing pipeline with integrated GMII/SGMII management paths, a host processor interface for configuration and telemetry, and table-based forwarding engines sized for Carrier Ethernet service queues. Because the four XAUI ports are consumed by 10 Gbps uplinks, port density on the copper side is decoupled from the number of physical network interfaces a chassis can present, allowing 1 Gbps access ports to be aggregated toward 10 Gbps or 40 Gbps backbones.
Typical deployments include telecom access and aggregation shelves, mobile backhaul concentrators, industrial Ethernet aggregation equipment, and enterprise campus access switches requiring 24 copper ports plus high-speed uplinks in a single module. The automotive temperature grade makes the device attractive for harsh-environment industrial and vehicle-network designs that require extended ambient operation.
One key design consideration is that the 672-pin HFCBGA demands a multilayer PCB with short, matched high-speed SerDes routing, controlled reference-plane design, and careful power and ground plane distribution around the SerDes sections. Layout should follow the manufacturer reference design for breakout of the XAUI lanes.

典型應用
VSC7460YIH 適用於 6 應用s: Telecom Carrier Ethernet Access Shelf, Mobile Backhaul Concentrator, Industrial Ethernet Aggregation Chassis, Enterprise Campus Access Switch, Vehicle Network Backbone Controller, Test and Measurement Front Panel.
Telecom Carrier Ethernet Access Shelf
The VSC7460YIH is designed for telecom access equipment where 24 copper Gigabit ports must be aggregated onto high-speed uplinks. Each 10/100/1000 Mbps copper port serves a subscriber or service card, while the four 10 Gbps XAUI lanes carry traffic toward the aggregation layer. Because the part is a Carrier Ethernet switch rather than a plain enterprise switch, service and port policing and traffic classification can be applied close to the access ports. Optional 2.5 Gbps breakout from two XAUI lanes allows a gradual migration path for customers moving above 1 Gbps without changing the switching silicon. The 672-pin HFCBGA footprint keeps the design compact relative to discrete PHY plus switch arrangements, which matters when line cards are only a few inches wide.
推薦
Mobile Backhaul Concentrator
Mobile backhaul equipment must aggregate many small eNodeB or small-cell links into a smaller number of high-capacity transport paths, and the VSC7460YIH fits that role directly. The 24 copper Gigabit ports accept base-station or small-cell fronthaul links, and the four 10 Gbps XAUI ports face the packetized backhaul or fronthaul concentrator card. This separation keeps the access-plane traffic isolated on deterministic copper links while concentrating it onto high-speed serial transport. The Carrier Ethernet feature set allows per-service QoS marking, protection switching and statistics that backhaul operators use for SLA reporting. The automotive temperature grade is a bonus for deployments in outdoor or vehicle-mounted small-cell cabinets that must operate across wide ambient temperatures.
推薦
Industrial Ethernet Aggregation Chassis
Industrial plants and factory floors need rugged aggregation equipment that combines many machine and sensor links with a fast uplink. The VSC7460YIH provides 24 Gigabit copper ports for PLCs, drives, vision systems and remote I/O, and uses its four XAUI 10 Gbps lanes to cascade several chassis or to feed a plant backbone. The automotive temperature grade extends the usable ambient range compared with a commercial-grade switch, which supports cabinet-mounted and outdoor-adjacent installations. Because the switch performs forwarding in dedicated hardware, latency and jitter stay predictable under heavy traffic, and the port-level statistics support diagnostic monitoring of production lines. Board designers should follow the manufacturer reference layout for the SerDes escape and provide filtered supplies per the reference schematic.
推薦
Enterprise Campus Access Switch
In an enterprise campus or data-centre access layer, the VSC7460YIH can present 24 Gigabit copper ports to workstations, phones and access points while concentrating uplinks onto the four 10 Gbps XAUI ports towards distribution and core layers. The hardware forwarding engine keeps latency low and frees the system controller from per-packet work, which matters when thousands of endpoints are aggregated behind the access layer. Optional 2.5 Gbps line rates are useful for wavefront Wi-Fi access points and multi-gigabit server connections that would otherwise require separate hardware. The four XAUI lanes also allow stacking-style topologies with predictable wire-speed behavior, and the 672-pin HFCBGA keeps the board footprint smaller than discrete switch-plus-PHY designs would be.
推薦
Vehicle Network Backbone Controller
The automotive temperature grade and lead-free construction of the VSC7460YIH make it a candidate for in-vehicle networking backbones where many ECUs need aggregated Ethernet connectivity. Twenty-four Gigabit ports can service cameras, radar and lidar front-ends, domain controllers and body modules, while the XAUI lanes move aggregated traffic toward the central compute domain. Vehicle environments demand stable behaviour over temperature extremes, which is exactly what the automotive-grade ordering code targets. The design must still respect the SerDes constraints of the package, so differential pair routing, reference planes and power filtering must follow the manufacturer reference design. Protocol handling and functional safety partitioning are handled at the system level above this device.
推薦
Test and Measurement Front Panel
Instrumentation and test equipment front panels often need a large number of low-speed control and measurement ports alongside a few very fast data paths. The VSC7460YIH can handle 24 copper Gigabit ports for instrument control, trigger distribution and remote interface traffic, then export data over the four 10 Gbps XAUI lanes to a host or storage subsystem. That split keeps deterministic control traffic on isolated copper links while bulk data moves over high-speed serial links, reducing contention and jitter in time-critical measurement paths. Carrier Ethernet classification features allow measurement data to be marked and queued separately from administrative traffic. Because the package is large and SerDes-sensitive, the board plan should be validated against the manufacturer reference design early in the mechanical layout phase.

主要差異化特點
- 24 copper Gigabit ports plus four 10 Gbps XAUI uplinks integrated on one device (對比Marvell 88E6390X)
- Optional 2.5 Gbps breakout without changing switch silicon (對比VSC7463YIH)

- Carrier Ethernet feature set in a single 672-pin HFCBGA (對比Multi-chip switch plus external PHY stacks)
設計說明
The four 10 Gbps XAUI lanes are the most demanding nets on this board. Route each differential pair over continuous reference planes with no plane splits, keep intra-pair skew well under the SerDes budget, and match the pair geometry to the connector or backplane channel. Break out of the 672-ball array on a multilayer stack-up that allows the SerDes escape without long stubs, and follow the manufacturer Jaguar-1 reference design for ball assignment and layer transitions rather than improvising a new escape topology.
A 672-ball HFCBGA with high-speed Serdes demands a multilayer PCB with via-in-pad or microvia structures under the array, a solid ground reference beneath the switch and dedicated power planes per supply domain. Provide dense thermal-via arrays into the ground plane region to spread heat out of the junction, and de-couple each supply rail locally with the capacitor values given in the reference schematic. Confirm the supported board outline, ball pitch and land pattern against the current manufacturer package drawing before releasing artwork.
Estimated: a 24-port switch with four active 10 Gbps uplinks draws well over 20 W in a full-load configuration, so the power tree must be sized for the worst case, not the typical case. With a 12 V intermediate rail and an assumed 80 percent conversion efficiency, delivering 25 W to the device requires roughly 31 W from the converter with about 6 W of loss. Size the input supply and copper pours for that continuous load, keep the converter loop compensation away from the SerDes reference planes, and use separate filtering paths for the digital and analog supply groups.
Do not treat the YI ordering suffix as a cosmetic mark: distributor records list this ordering code with an automotive temperature grade, and the same family is also sold in other grades and package variants. Confirm the exact suffix, ball finish and moisture sensitivity level from the current manufacturer ordering information before committing to production. A common field failure mode is substituting a same-port-count but different-footprint switch such as a 516-BGA device, which cannot be soldered onto this land pattern and forces a full board redesign.
合規資訊
Distributor listings explicitly state Pb Free for the VSC7460YIH and describe an automotive temperature grade, but no RoHS, REACH, halogen-free or AEC-Q100 statement appears in the product information for this ordering code; confirm these with the manufacturer before release to production.
