DP83910AV Overview
A Serial Network Interface is an interface integrated circuit that converts between a host-side digital data stream and the physical signaling required by a legacy Ethernet network. In the product hierarchy, SNI belongs to network interfaces, then interface ICs, then integrated circuits. Manchester encoding represents each data bit through a transition pattern, allowing the receiver to recover both the bit value and clock information from the serial waveform. This device is therefore intended for systems requiring legacy Ethernet-compatible Manchester encoding and decoding rather than a modern integrated PHY/MAC solution.
The DP83910AV is specified as a 28-pin PLCC device, with the AV suffix identifying the supplied package/orderable configuration. Its 4.75 V to 5.25 V operating range is characteristic of a 5 V legacy interface implementation. Distributor listings classify the device as an Ethernet Network Interface IC, while the manufacturer-related datasheet description identifies it as a CMOS SNI Serial Network Interface. The available source data does not provide verified values for clock rate, current consumption, output timing, logic levels, or internal transceiver details.
Typical engineering uses include legacy Thin Ethernet network nodes, industrial data-collection equipment, embedded test systems, and retrofits requiring compatibility with existing Manchester-encoded Ethernet hardware. In such systems, the DP83910AV can perform the Manchester encoding or decoding stage at the boundary between digital logic and the network interface. The 28-PLCC package is a legacy surface-mount format requiring a matching footprint, adequate routing clearance, and careful examination of pin orientation and thermal performance.
For new designs, verify that the required legacy network architecture, voltage, timing, connector, and isolation requirements match the device. Obsolete or NRND legacy Ethernet components should be sourced only after confirming documentation, traceability, and long-term availability. The available distributor result reports 6,224 pieces in stock and a unit price of $9.5471, but price and availability should be reconfirmed at the time of purchase.

DP83910AV qccj Pin Configuration Guide
Pin configuration for DP83910AV (qccj package). Pin numbering, functions, and connection diagrams are defined in the manufacturer datasheet. Refer to it for the exact footprint and soldering guidelines.
No detailed pinout data available for DP83910AV.
Refer to the datasheet for full pin configuration.
Typical Applications
DP83910AV is suitable for 6 applications: Legacy Thin Ethernet Node, Industrial Data Collection, Embedded Test Equipment, Retrofit of Existing Ethernet Hardware, Legacy Network Interface Demonstration, Legacy Control-System Adapter.
Legacy Thin Ethernet Node
The DP83910AV fits a legacy Thin Ethernet node that requires IEEE 802.3 Manchester encoding and decoding at the interface boundary. Its verified 4.75 V to 5.25 V supply range and 28-PLCC package match systems built around a 5 V interface architecture. Place the device where the host logic and network-specific interface circuitry meet, and verify the complete timing and pin definitions against the manufacturer documentation. The main engineering benefit is preservation of an established Manchester-based network path rather than introduction of a modern PHY architecture.
Recommended
Industrial Data Collection
DP83910AV can be considered for industrial data-collection equipment that retains a legacy Ethernet-compatible SNI architecture and operates within the verified 0 C to 70 C commercial temperature range. The part’s Manchester encoding and decoding role can support a defined network segment when existing hardware already expects that signaling method. The design must account for enclosure temperature, grounding, cable protection, and the difference between commercial-temperature operation and a fully qualified industrial component. Verify obsolete-product sourcing before committing to long production runs.
Recommended
Embedded Test Equipment
The DP83910AV is suitable for test equipment that must emulate or communicate with a legacy Manchester-encoded Ethernet interface. Because it is identified as a CMOS SNI, the device can serve as a functional building block when the tester already defines the expected physical signaling and timing. The 28-PLCC footprint requires careful board layout and access to the original pinout, while the 4.75 V to 5.25 V range supports 5 V test-system rails. Confirm signal levels, timing margins, and isolation requirements before hardware release.
Recommended
Retrofit of Existing Ethernet Hardware
DP83910AV is most relevant when repairing or extending a board that was designed around the DP83910A family and cannot accept a footprint or signaling redesign. Its 28-PLCC J-lead package and legacy Manchester SNI role allow a targeted replacement strategy if the exact pinout, timing, supply, and lifecycle requirements are confirmed. A retrofit should not be based only on the Ethernet label: compare the original schematic and manufacturer datasheet, check obsolete-part markings, and inspect incoming devices. The main benefit is preserving an existing PCB architecture while managing sourcing risk.
Recommended
Legacy Network Interface Demonstration
The DP83910AV can support an educational or laboratory demonstration of legacy Ethernet signaling because the supplied description identifies Manchester encoding and decoding and IEEE 802.3 Thin Ethernet compatibility. A demonstration board can expose the SNI function beside a host controller and measurement equipment, allowing engineers to study waveform behavior and timing. The commercial 0 C to 70 C range is suitable for a controlled lab environment. Use a documented interface circuit and current datasheet; do not infer connector, isolation, or transceiver requirements from the package description alone.
Recommended
Legacy Control-System Adapter
The DP83910AV may fit an adapter that connects a control or monitoring system to an existing Manchester-based Ethernet network segment. Its 4.75 V to 5.25 V operating range aligns with a 5 V interface design, while the CMOS SNI function handles the network encoding or decoding role. The adapter designer must validate electrical timing, cable and connector requirements, isolation, and thermal conditions against the original system. Because the part is NRND, use it primarily for compatibility work and plan a documented migration path rather than designing a new long-life platform around it.

Design Notes
Do not substitute a part based only on the Ethernet label or the 28-PLCC package. The verified data does not provide the complete DP83910AV pinout, timing table, logic levels, or absolute electrical limits. Before layout or replacement, obtain the manufacturer datasheet, compare every pin, power rail, clock or timing signal, Manchester-interface connection, and no-connect position. Pay particular attention to the distinction between the DP83910A family name and the DP83910AV orderable suffix.
Treat the DP83910AV as a legacy 28-PLCC J-lead device. Confirm the exact footprint, pin-1 orientation, pad geometry, solder-mask clearance, and thermal-via strategy against the package drawing before release. Place signal and power connections in accordance with the original reference design, and preserve adequate creepage and clearance for the network and power sections. The verified web data identifies J-bend terminals and QCCJ package coding but does not provide a land pattern, so the missing dimensions must be obtained from official documentation.
The verified operating-temperature classification is 0 C to 70 C, which should be used as the initial environmental boundary for commercial applications. For higher enclosure temperatures, calculate the device dissipation from the actual supply, load, and operating conditions and compare the resulting junction estimate with the manufacturer’s thermal limits. Because no power dissipation, thermal resistance, or maximum junction-temperature values are supplied here, no thermal estimate is asserted. Validate the assembly with thermal testing and obtain the original package thermal data before production.
The DP83910AV is verified for a 4.75 V to 5.25 V supply range, so the surrounding circuit must remain within that range during startup, fault recovery, and normal operation. Check the regulator’s tolerance, transient response, decoupling strategy, and sequencing against the device’s original application circuit. Do not assume that a modern Ethernet controller’s power requirements are compatible merely because both systems use a nominal 5 V rail. The supplied data does not identify current consumption or power sequencing requirements.
Because the manufacturer support search identifies DP83910AV as NRND and the independent substitute search did not identify a confirmed compatible device, lifecycle management is part of the design. Record the exact ordering suffix, obtain authorized sourcing, inspect incoming material, and create a controlled end-of-life or migration plan. Avoid treating distributor stock or a related suffix as proof of future availability. The available pages report sourcing activity and one price, but current inventory and long-term supply remain unverified.
Compliance Information
The supplied verified data does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for DP83910AV. No compliance claim is inferred.
