DP83223V-1 - 100 Mbps Ethernet Transceiver | Texas Instruments
MPN： DP83223V-1 ✗ 停產DP83223V-1 概覽
An Ethernet physical-layer transceiver converts logical data into signals suitable for a network cable and converts returning signals into data for the associated media-access controller. The DP83223V family supports 10 Mbps and 100 Mbps operation, according to the verified distributor specifications. Its single-port architecture serves legacy Fast Ethernet equipment rather than gigabit networks, so PHY function, cable topology, and controller support must be checked before modern system integration.
The verified listings identify the device as an Ethernet transceiver with one port, a 5 V supply, and a 100 Mbps maximum listed data rate. The target ordering code DP83223V-1 is listed by DigiKey through Rochester Electronics. The base DP83223V is also listed by DigiKey in a 28-pin PLCC package, providing a useful package reference for design review. Detailed electrical limits, termination requirements, transmit-drive strength, receiver thresholds, temperature range, and exact pin names were not included in the supplied source data and therefore are not inferred here.
DP83223V can be evaluated in legacy 10/100-Mbps endpoint, network-interface-card, hub-interface, switch-interface, and industrial-retrofit designs when the surrounding controller and magnetics are compatible with the original Twister architecture. Designers should not substitute it for a gigabit PHY because the verified maximum data rate is 100 Mbps. Likewise, an SOHO or industrial controller must support the same line coding, signaling, isolation, and termination arrangement before the transceiver is selected.
The principal design consideration is that a transceiver is only one element of an Ethernet physical layer. The line interface also depends on transformer or magnetics, termination network, connector, controlled-impedance printed circuit board, grounding, and electromagnetic-compatibility design. Follow the manufacturer datasheet for pin connections and application circuitry. Because the exact schematic and pin table were not supplied, validate the complete interface against the current manufacturer documentation rather than relying on distributor summaries.
This page consolidates verified distributor identification, sourcing links, package information, and engineering-selection guidance. It does not invent missing timing, electrical, compliance, lifecycle, or pricing values; those fields remain explicitly unresolved where the supplied evidence is insufficient. That distinction is especially important for an older networking transceiver, where exact revision behavior and sourcing status can determine whether a legacy design remains electrically and commercially reproducible.

典型應用
DP83223V-1 適用於 6 應用s: Legacy Fast Ethernet Network Interface, Network Interface Card Retrofit, Industrial Ethernet Equipment Retrofit, Hub and Switch Interface Maintenance, Embedded Control Communication Port, Legacy Network Test Equipment.
Legacy Fast Ethernet Network Interface
The DP83223V-1 fits a legacy 10/100-Mbps Ethernet interface when the associated controller and line network match the Twister transceiver architecture. Its verified single-port and 100 Mbps classifications support Fast Ethernet physical-layer operation, while the 5 V supply suits an older 5 V equipment design. The board must reproduce the manufacturer's pinout, magnetics, termination, and layout because the supplied sources do not expose a complete 28-pin connection table or permit automatic substitution.
推薦
Network Interface Card Retrofit
DP83223V-1 can be evaluated for a network-interface-card retrofit that still uses one 10/100-Mbps twisted-pair port and requires the original National Semiconductor interface. Its verified 5 V operation and maximum listed 100 Mbps rate fit the broad class of legacy PCI or embedded network adapters, but the specific host-side controller remains unknown. Maintenance engineers should preserve the original footprint, connector wiring, isolation components, and controller timing rather than treating the transceiver as a complete network card.
推薦
Industrial Ethernet Equipment Retrofit
The DP83223V-1 is applicable to maintenance of legacy industrial equipment that exposes a single 10/100-Mbps twisted-pair Ethernet port. The verified 100 Mbps capability can preserve an existing Fast Ethernet link, while the PLCC package supports repair sourcing through specialized channels. Industrial adoption should additionally check temperature limits, isolation, emissions, grounding, and cable-port protection, because none of those ratings were included in the supplied distributor evidence.
推薦
Hub and Switch Interface Maintenance
A legacy hub or switch line card may use DP83223V-1 to maintain one 10/100-Mbps copper port during repair or replication. Its one-port format maps naturally to a per-port PHY section, and the verified 28-pin PLCC package provides a defined mechanical target for an existing design. Before assembly, verify controller compatibility, line coding, isolation, termination values, clocking, and signal-integrity layout against the original design because these details are absent from the supplied snippets.
推薦
Embedded Control Communication Port
DP83223V-1 can support an embedded controller’s legacy 10/100-Mbps communication port when preserving the original Twister-based hardware is more important than modern PHY integration. Its verified 5 V supply and 100 Mbps maximum data rate align with older embedded Ethernet systems. The implementation still needs a compatible media-access controller, magnetics, termination, and connector; a processor with an integrated MAC can be used only when its electrical interface and timing match the transceiver.
推薦
Legacy Network Test Equipment
DP83223V-1 may be useful when repairing a 10/100-Mbps network test fixture or interface module built around the original transceiver. A single-port device simplifies replication of an existing copper-link test channel, and its verified maximum rate of 100 Mbps defines the supported link class. Instrument designers should account for isolation, controlled-impedance routing, calibration or loopback requirements, and connector creepage, none of which can be quantified from the supplied data.

設計說明
Treat the DP83223V-1 copper interface as a controlled-impedance high-speed design, not as ordinary digital routing. The verified device supports rates up to 100 Mbps and uses a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. Follow the manufacturer reference layout exactly for differential or network-line routing, maintain continuous reference planes, minimize stubs, and preserve the original magnetics and termination geometry. The supplied data does not contain trace impedance or spacing values, so obtain those from the manufacturer rather than estimating them.
Do not assume that DP83223V is a drop-in substitute for DP83223V-1 or that a similarly named 28-pin PLCC Ethernet device is compatible. The verified sources establish the package and link-rate class but do not explain the -1 suffix or provide a complete pin table. Before substitution, compare the ordering code, pin names, electrical ratings, controller interface, line coding, magnetics, termination, and footprint. This prevents a package-level match from becoming a board-level failure.
The verified supply requirement is 5 V, but current consumption, allowable tolerance, sequencing, and decoupling values are not supplied. Power the transceiver through a quiet 5 V rail and follow the manufacturer's recommended bypass network with short, low-inductance connections. Because this is a legacy physical-layer device, unstable supply voltage can affect transmit levels, receive thresholds, and error rate even when nominal 5 V operation appears correct. Validate conducted emissions and sensitivity in the finished enclosure.
合規資訊
The supplied distributor and search snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values remain unknown rather than being inferred from the manufacturer or age of the device.
