DP83223V 概述
A network transceiver is an interface IC that combines transmitter and receiver functions for high-speed wired communications. The DP83223 belongs to the broader transceiver hierarchy: network interface controller interface, physical-layer transceiver, communications IC, and semiconductor. Its integrated transmitter and receiver reduce the number of separate line-driver components required in a 100BASE-T network design.
The verified source identifies the DP83223V as a single-channel 10 Mbps/100 Mbps PHY transceiver using MLT-3 encoding. It also identifies a 28-pin PLCC package and 28 pins. Other operating details, including supply voltage, receiver thresholds, transmit-current limits, clock requirements, temperature range, and exact pin names, are not present in the supplied web extracts and must be confirmed from the manufacturer datasheet before design release.
Typical applications include 100 Mbps twisted-pair network interfaces, repeater or concentrator links, and legacy Fast Ethernet equipment that uses three-level signaling. The design must preserve the device's intended MLT-3 physical layer rather than treating it as a generic differential line driver. Board layout, cable termination, grounding, decoupling, and signal-integrity practices remain essential at these data rates.
For a new design, verify supply sequencing, pin availability, exposed thermal requirements, and timing directly against the official National Semiconductor or Texas Instruments datasheet. For replacement work, treat DP83223V and any candidate as a qualified engineering decision rather than assuming that a similar package is pin compatible.
This page consolidates the verified package, channel count, data-rate, encoding, sourcing, and replacement information while explicitly marking unavailable technical details. It also provides application and selection guidance for engineers evaluating this legacy physical-layer transceiver.

典型应用
DP83223V 适用于 6 应用s: Legacy 100 Mbps Twisted-Pair Interface, 10 Mbps Backplane-Style Network Link, Fast Ethernet Concentrator Link, Legacy Network Adapter Upgrade, Twisted-Pair Test Equipment Interface, Industrial Retrofit with Legacy Ethernet.
Legacy 100 Mbps Twisted-Pair Interface
The DP83223V is a one-channel 10 Mbps/100 Mbps transceiver using three-level MLT-3 signaling, making it relevant to legacy twisted-pair physical-layer links. Place it between the network controller and the cable-side transmit/receive circuitry where the system expects the DP83223's established three-level waveform. The verified package is a 28-pin PLCC measuring 11.51 mm by 11.51 mm. Before layout release, confirm voltage, timing, termination, receiver thresholds, and every pin function from the manufacturer datasheet; these details are not supplied in the verified excerpts.
推荐
10 Mbps Backplane-Style Network Link
The DP83223V supports the verified 10 Mbps operating rate and integrates transmit and receive functions for three-level MLT-3 data streams. This makes it applicable to older network equipment designed around a dedicated physical-layer transceiver rather than a modern multi-standard PHY. The design must match the original controller's data timing and MLT-3 encoding assumptions. Because the supplied sources do not state supply voltage, receiver thresholds, output levels, or temperature limits, prototype decisions should be validated against the manufacturer datasheet and measured with the intended cable and termination network.
推荐
Fast Ethernet Concentrator Link
The single-channel DP83223V can serve as the physical-layer building block in a legacy Fast Ethernet concentrator or repeater-style design that uses MLT-3 signaling. Its integrated transceiver arrangement simplifies the allocation of separate line-driver and receiver functions, while the 28-pin PLCC package supports a conventional through-hole board footprint. A working product must still account for cable loss, termination, isolation or protection, grounding, and signal timing. The verified data confirms the package and rate but does not provide complete loopback, skew, or jitter figures for a production design.
推荐
Legacy Network Adapter Upgrade
The DP83223V is useful when repairing or extending equipment built around its original MLT-3 twisted-pair transceiver architecture. The verified 10 Mbps/100 Mbps capability allows the same device class to address two legacy link rates, provided the associated controller and external circuitry are designed for the correct encoding and timing. A replacement effort should verify the exact MPN, package marking, pinout, supply rails, and thermal requirements. The supplied excerpts do not establish current lifecycle status, so obsolete or excess-inventory sourcing must be confirmed before committing to a new product.
推荐
Twisted-Pair Test Equipment Interface
The DP83223V can be evaluated in laboratory or production test fixtures that reproduce a legacy MLT-3 twisted-pair physical layer. Its integrated transmitter and receiver provide a convenient device-level target for signal-integrity characterization, cable testing, and fault isolation. The test fixture must use the manufacturer's specified supply, termination, loading, and measurement setup; the supplied web data does not provide those values. Treat the 10 Mbps and 100 Mbps ratings as supported operating modes, not as permission to omit timing, eye, jitter, or return-loss validation.
推荐
Industrial Retrofit with Legacy Ethernet
The DP83223V may assist in a retrofit that must preserve an existing MLT-3 twisted-pair interface while adding monitoring or control around a legacy network subsystem. Its one-channel architecture is appropriate where the design needs one transmit/receive path rather than a multi-port switch. The device should be paired with the original controller timing and cable termination, and its 28-pin PLCC footprint must remain unchanged for a board-level drop-in attempt. Verify operating temperature, supply voltage, isolation, ESD protection, and procurement status because these parameters are not provided in the verified search excerpts.

关键差异点

- Known package and footprint target （对比 DP83223V-1)
- Single-channel legacy network use （对比 DP83223V-1)
设计说明
The DP83223V is an MLT-3 physical-layer transceiver, so the PCB must preserve the original three-level waveform and controlled-impedance path to the twisted-pair interface. Before layout, obtain the manufacturer pinout and reference circuit values; the supplied excerpts do not specify trace geometry, termination, or receiver thresholds. Keep the cable-side route short, provide the required termination network, and validate rise time, overshoot, ringing, eye opening, and jitter with the intended cable.
The 28-pin PLCC footprint is a board-commitment decision. Confirm pin numbering, pin names, power pins, ground distribution, and unused-pin requirements directly from the manufacturer datasheet before placing the footprint. Do not infer a generic PLCC mapping from the package dimensions. For a retrofit, compare the existing board artwork, solder side, pin-1 orientation, and any exposed thermal or mechanical features before treating a replacement as drop-in.
The supplied data identifies the DP83223V as a 10 Mbps/100 Mbps MLT-3 transceiver but does not provide its supply voltage or current limits. Determine those values from the manufacturer datasheet, then verify the board's regulator capacity, startup behavior, bypass capacitors, and noise margin. Do not reuse a modern PHY's supply arrangement by assumption: the PLCC transceiver, its controller, and its cable-side interface may require different rail sequencing and grounding.
