DP83223VB - High-Speed Twisted-Pair Transceiver | National Semiconductor
MPN： DP83223VB ✗ 停產DP83223VB 概覽
What is a twisted-pair transceiver? A twisted-pair transceiver is a physical-layer interface device that converts between digital logic signals and the electrical signaling used by a copper network medium. The DP83223VB belongs to the broader sequence of networking transceiver, physical-layer interface, communications IC, and semiconductor categories. Its MLT-3 three-level signaling capability distinguishes it from conventional binary line-driver circuits and makes signal-level compatibility, cable characteristics, termination, and timing central to successful implementation.
The supplied search results describe the DP83223 family as capable of driving and receiving MLT-3 encoded datastreams. They do not provide verified values for operating voltage, maximum data rate, receiver sensitivity, transmitter output level, pin assignments, package dimensions, temperature range, or power consumption. Those parameters must therefore be taken from the manufacturer documentation rather than inferred from the distributor title. The verified listing also associates DP83223VB with an Ethernet transceiver classification, although the family material uses the broader TWISTER networking-transceiver description.
This device is relevant to legacy high-speed network equipment, telecom interfaces, industrial communications, communications equipment, wireless infrastructure, connected peripherals, and other systems that use compatible MLT-3 physical-layer signaling. Its PLCC package provides a through-hole-style leaded package suitable for established PCB layouts, but the exact pinout must be checked before substitution. A distributor result reports the part as listed under Rochester Electronics, while the original manufacturer identity is National Semiconductor, later associated with Texas Instruments in the search results.
The most important design consideration is avoiding assumption-based replacement. Because the verified material does not establish that any alternative shares the exact 28-pin PLCC footprint and pinout, replacement should be treated as an engineering comparison requiring datasheet verification. Review signal polarity, supply rails, timing, termination, isolation, exposed-pad requirements, and PCB land pattern before approving a substitute.
This page combines the verified distributor and manufacturer-family references with explicit data gaps, package-level selection guidance, and sourcing links for engineers evaluating DP83223VB availability, datasheet access, and drop-in replacement decisions.

典型應用
DP83223VB 適用於 6 應用s: Legacy High-Speed Network Interfaces, Telecom Equipment Interfaces, Industrial Communication Equipment, Communications Equipment Maintenance, Wireless Infrastructure Interfaces, Legacy Connected Peripherals.
Legacy High-Speed Network Interfaces
The DP83223VB fits a legacy communications board requiring a dedicated physical-layer path for MLT-3 encoded data. Its verified family description confirms transmit and receive capability, while the 28-pin PLCC package suggests a through-hole or leaded implementation suitable for established network-interface layouts. The designer must still verify supply rails, timing, termination, and pin functions from the exact manufacturer documentation. This is not a modern Ethernet PHY claim; the verified material supports a TWISTER high-speed networking-transceiver role with MLT-3 signaling. Existing equipment refreshes, telecom interface assemblies, and industrial communication controllers are the most relevant uses when their original system architecture uses this physical-layer device.
推薦
Telecom Equipment Interfaces
The DP83223VB is relevant to telecom equipment that uses a compatible MLT-3 physical layer and requires separate transmit and receive handling. The distributor classification identifies the part as a telecom IC and Ethernet transceiver, while the family material describes it as a high-speed networking transceiver. Before selecting it, engineers should confirm the exact data rate, signal thresholds, isolation requirements, connector interface, and power specifications from the datasheet. A replacement board can use this device only when the original design's signal topology and termination scheme are preserved. It is best suited to legacy telecom equipment and communication infrastructure rather than newly designed low-voltage edge devices.
推薦
Industrial Communication Equipment
DP83223VB can be evaluated for industrial communication equipment when the existing architecture uses MLT-3 signaling and the 28-pin PLCC footprint is already present. Its verified function supports driving and receiving three-level encoded datastreams, which can simplify integration into a fixed legacy physical-layer design. However, the supplied data does not confirm industrial temperature grade, isolation, ESD ratings, or modern Ethernet compliance. Therefore, use it only when those requirements are covered by the exact part documentation. For new industrial products, compare the legacy device against current Ethernet controllers and transceivers rather than assuming functional interchangeability. PCB compatibility is the decisive criterion.
推薦
Communications Equipment Maintenance
The DP83223VB is a practical candidate for maintenance and repair of communications equipment that already uses this exact National Semiconductor device or an equivalent documented footprint. The verified distributor listing provides a route to quote and stock checking, which is useful when restoring older network-interface assemblies. Because the source does not provide a complete pinout or lifecycle statement, technicians should verify markings, package type, and ordering suffixes before installation. Avoid substituting a superficially similar transceiver until signal levels, timing, and pin functions are proven equivalent. This application emphasizes preservation of established boards rather than new feature design.
推薦
Wireless Infrastructure Interfaces
The DP83223VB may appear in older wireless-infrastructure equipment that uses compatible high-speed copper physical-layer links. The verified result explicitly associates the device with communications equipment and wireless infrastructure applications, but it does not provide RF specifications or confirm that the transceiver is an RF component. Treat the device as a digital networking interface only. Any design must verify the original system's MLT-3 topology, cable length, connector, termination, and timing against the exact manufacturer specifications. For new wireless-infrastructure equipment, a current Ethernet interface solution may offer better documentation and lifecycle support, so DP83223VB is best treated as a legacy or repair component.
推薦
Legacy Connected Peripherals
DP83223VB can support a connected peripheral or communications adapter designed around MLT-3 physical signaling and the verified 28-pin PLCC package. The device's transmit and receive functions make it suitable for evaluating board-level repairs or expansions in older equipment. The supplied snippets do not establish USB, storage, or peripheral-interface compatibility, so it should not be marketed as a general-purpose peripheral controller. Confirm the original system's data standard, voltage levels, connector requirements, and timing first. When preserving an existing board, exact footprint and pin compatibility matter more than generic transceiver functionality. A schematic review and continuity check should precede any substitution.

設計說明
Do not treat the family name DP83223 or the related listing DP83223V as proof that every ordering suffix is interchangeable with DP83223VB. The verified data establishes the 28-pin PLCC format and MLT-3 transmit/receive function, but it does not provide the complete pinout or suffix comparison. Before ordering or soldering, confirm the exact manufacturer part number, package drawing, pin functions, electrical limits, and lifecycle status.
Preserve the manufacturer-documented PLCC land pattern and pin numbering rather than using the qfn-28 diagram key as a physical footprint. The selected package key is only a visualization placeholder because the verified source identifies PLCC, not QFN. Review connector pinout, ground-return paths, and the original MLT-3 termination network with the exact application circuit before modifying a legacy board.
MLT-3 operation depends on the physical medium, termination, signal levels, and timing budget. The supplied material confirms three-level datastream drive and receive but does not specify rise time, jitter, output amplitude, receiver thresholds, or maximum cable length. Measure or simulate those values from the manufacturer datasheet and reference design before assuming that a board-level replacement will preserve signal integrity.
The verified data does not state DP83223VB supply voltage or power consumption, so power-tree design cannot be completed from the available snippets. Identify the exact rails and sequencing requirements from the manufacturer datasheet, then verify absolute maximum voltage, operating voltage, and current margin at every line rate. Do not substitute a similar transceiver based only on its Ethernet or communications classification.
合規資訊
The verified snippets do not provide compliance declarations for National Semiconductor DP83223VB. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status must be confirmed from the exact manufacturer or authorized distributor documentation.
