VSC7323VH - 10G Ethernet MAC Controller | Microchip
Teilenummer: VSC7323VH ✓ AktivVSC7323VH Übersicht
An Ethernet MAC controller is an interface IC that manages communication between a host or switching subsystem and physical Ethernet interfaces. Within the semiconductor hierarchy, it belongs to the Ethernet interface-controller class, which sits under network interface ICs and broader communication semiconductors. The VSC7323VH is intended for demanding systems that require a consolidated 10G MAC function alongside multiple 1G Ethernet connections.
Key features include ten integrated 1G Ethernet MAC positions, one 10G Ethernet MAC function, a 2.5 V or 3.3 V I/O operating range, and an industrial temperature rating to +85 °C. Its 0.18-micron CMOS implementation reflects the process technology used for this generation of high-integration networking silicon. The five-pin JTAG interface supports boundary-scan-oriented manufacturing and test access.
The 728-pin TBGA package provides extensive high-speed connectivity for parallel or otherwise complex networking interfaces. Its 42.5 mm by 42.5 mm body is substantially larger than common QFN and QFP packages, reflecting the high pin count and routing demands of the device. Board design must consequently address dense escape routing, controlled-impedance links, via arrays, return-path continuity, and power-distribution integrity.
Typical applications include enterprise and metro Ethernet switching platforms, multi-service provisioning equipment, industrial networking systems, and telecommunications access products. The combination of ten 1G and one 10G MAC channel can reduce the number of discrete interface devices required in a line-card or switching subsystem while retaining dedicated test access through JTAG.
Designers should verify the original Vitesse Semiconductor datasheet, signal-integrity requirements, pin assignment, and power sequencing before layout. Because this 728-pin TBGA has a large ball array, manufacturing capability, via-in-pad suitability, thermal management, and X-ray inspection requirements should be confirmed with the PCB assembler. Commercial availability and pricing are quote-based in the supplied market data.
This page consolidates verified distributor listings, the available VSC7323 datasheet information, package constraints, procurement details, and a qualified drop-in comparison. It also separates confirmed specifications from unavailable electrical parameters, helping engineers evaluate the VSC7323VH without mistaking unsupported values for manufacturer guarantees.

Typische Anwendungen
VSC7323VH ist geeignet für 6 Anwendungs: Enterprise Ethernet Switching, Metro Ethernet Access Equipment, Multi-Service Provisioning Platforms, Industrial Network Gateways, Network Processor Line Cards, Communications Test Equipment.
Enterprise Ethernet Switching
The VSC7323VH fits enterprise switch line cards that need one high-speed 10 Gb/s MAC path alongside ten 1 Gb/s MAC channels in a single device. Its documented 2.5 V or 3.3 V I/O operation and industrial temperature maximum of +85 °C align with equipment-room requirements. The 728-pin TBGA provides the extensive connectivity expected for a multi-port networking processor, but its 42.5 mm square footprint requires careful layer planning, controlled-impedance routing, and assembly validation. Software and board support for the specific VSC7323 revision must also be confirmed before adoption.
Empfohlen
Metro Ethernet Access Equipment
VSC7323VH is applicable to metro Ethernet access platforms requiring a combination of one 10 Gb/s uplink and ten 1 Gb/s service connections. Consolidating these MAC functions into one 0.18-micron CMOS device can simplify system partitioning when the product already supports the VSC7323 architecture. The documented +85 °C maximum temperature suits many indoor telecom environments, while 2.5 V and 3.3 V I/O options support mixed interface requirements. Designers still need the full power, clock, SerDes, and thermal specifications before releasing a production schematic.
Empfohlen
Multi-Service Provisioning Platforms
The ten 1 Gb/s MAC channels and one 10 Gb/s MAC channel of VSC7323VH align with multi-service provisioning platforms that aggregate multiple access services while retaining a high-capacity uplink. Its five-pin P1149.1 JTAG test port can support controlled manufacturing test access, and operation to +85 °C covers typical indoor telecommunications environments. The 728-pin TBGA requires a high-layer-count PCB with dense escape routing, short clock distribution, robust decoupling, and assembly inspection. Exact protocol support, internal memory, and performance data were not included in the verified excerpts.
Empfohlen
Industrial Network Gateways
VSC7323VH can support industrial gateways that combine a 10 Gb/s backbone connection with ten 1 Gb/s equipment-facing Ethernet MAC functions. The confirmed industrial maximum of +85 °C is relevant to controlled industrial enclosures, and the device's 2.5 V or 3.3 V I/O operation allows integration with compatible networking circuitry. Because the package contains 728 terminals and occupies 42.5 mm by 42.5 mm, the PCB should provide generous via access, carefully modeled impedance, independent clock and power distribution, and sufficient thermal spreading. Other environmental and lifetime requirements must be verified separately.
Empfohlen
Network Processor Line Cards
The VSC7323VH is well matched to legacy network-processor line cards that need numerous 1 Gb/s MAC interfaces plus a dedicated 10 Gb/s path. Its one 10G and ten 1G configuration consolidates packet-interface functions in a single 728-pin TBGA, while the JTAG test port provides a defined manufacturing-test attachment. A board using this device should reserve continuous high-speed reference planes, carefully route clocks, separate sensitive and noisy supplies where practical, and provide robust thermal vias. Software image availability, errata, and exact revision behavior remain critical qualification items.
Empfohlen
Communications Test Equipment
VSC7323VH may be incorporated into communications test equipment that must expose one 10 Gb/s test path and ten 1 Gb/s Ethernet channels through a common controller. The available industrial maximum of +85 °C can accommodate controlled test-system environments, and the five-pin JTAG interface simplifies production board test and debug access. The device's large 728-pin TBGA demands careful impedance modeling, low-noise reference distribution, and repeatable assembly inspection. Before using it as the measurement-facing controller, engineers should confirm PHY support, latency behavior, traffic-control features, and whether the test application has an established VSC7323 software model.

Wichtigste Unterscheidungsmerkmale

- Maintains the same physical footprint for board reuse (vs. VSC7323VH-03)
- Provides a defined manufacturing-test connection (vs. VSC7323VH-03)
Designhinweise
Reserve routing and via resources for the complete 728-terminal TBGA rather than treating it as a conventional perimeter BGA. Use short escape paths, multiple escape rows where necessary, and a via strategy validated by the PCB assembler. The 42.5 mm x 42.5 mm body also requires placement planning against connector keepouts, heatsinks, chassis hardware, and neighboring components.
Model every high-speed Ethernet and clock trace as a controlled-impedance interconnect, with continuous reference planes and no plane splits beneath the device. Keep bypass connections extremely short and validate them against the manufacturer’s complete power and decoupling tables. The supplied data confirms 2.5 V or 3.3 V I/O operation but does not specify core voltage, clocking, SerDes rates, or recommended layouts.
Calculate dissipated power only after obtaining the missing core, I/O, and current specifications from the manufacturer datasheet. The device operates to +85 °C and uses a large TBGA, so thermal performance depends on the PCB copper area, via count, airflow, and the enclosure. Use Estimated: Pdiss = VIN × IIN after the actual operating conditions are known, then verify junction temperature against the applicable device limit.
Do not assume that VSC7323VH-03 is electrically identical to VSC7323VH solely because the package matches. Review the manufacturer revision history, errata, firmware or software-image requirements, temperature grade, and sourcing traceability before substitution. Likewise, do not populate undocumented power pins or infer the 728-pin assignment from generic TBGA conventions.
Compliance-Informationen
A distributor listing exposes RoHS and lead-free status fields, but the supplied excerpts do not state their values. No compliance claim has therefore been inferred. AEC-Q100 is not applicable to this industrial networking controller unless a separately qualified ordering option is documented.
