DP8392CN-1 概要
A coaxial transceiver interface is an interface IC that integrates the electrical functions needed to communicate over a shielded coaxial cable. In the broader networking hierarchy, it belongs to the network-interface and communications-semiconductor categories, where a physical-layer transceiver works alongside a network controller or system data bus. The DP8392CN-1 is therefore most useful when maintaining, repairing, or reproducing a legacy 10BASE-2 Ethernet design rather than designing a new modern Ethernet system. Its 16-DIP package favors through-hole construction and serviceable legacy equipment.
Key verified attributes include the 16-terminal rectangular DIP package, through-hole terminal form, nominal -9 V negative supply, commercial temperature grade, and a listed 19.305 mm length. The device is identified as suitable for Ethernet transceiver applications and supports the coaxial cable line-driver and receiver function. The verified data does not provide output impedance, propagation delay, receiver sensitivity, isolation voltage, or detailed timing values, so those parameters should not be inferred from the product family without an applicable manufacturer document.
Typical applications include legacy Thin Ethernet terminal adapters, coaxial network-interface cards, industrial or communications equipment retaining a 10BASE-2 port, and repair or restoration of older Ethernet hardware. The -9 V supply requirement must be checked against the surrounding circuit; it is not a modern 3.3 V or 5 V plug-in-compatible rail. The 16-pin through-hole footprint also requires mechanical and pin-level verification before replacement.
The most important design consideration is that a coaxial transceiver is not interchangeable with every Ethernet transceiver having the same network function. Confirm the exact pinout, supply polarity, cable termination, connector type, and signal-level requirements in the applicable datasheet before layout or schematic changes. For new designs, verify that the legacy 10BASE-2 requirement is intentional; modern 10/100/1000 Ethernet generally uses different physical-layer devices.
This page combines the verified distributor and manufacturer-source identification with package, application, and sourcing context. It distinguishes confirmed DP8392CN-1 facts from parameters that remain unavailable, rather than filling gaps with assumptions or unsupported substitutions.

主な用途
DP8392CN-1 の用途: 6 件s: Legacy 10BASE-2 Ethernet Adapter, Thin Ethernet Network Interface Card, Industrial Control-System Retrofit, Legacy Coaxial Bus Test Equipment, Communications Equipment Restoration, Educational and Prototype Ethernet Demonstrators.
Legacy 10BASE-2 Ethernet Adapter
The DP8392CN-1 fits a legacy Thin Ethernet adapter that must preserve an IEEE 802.3 coaxial physical layer. Its CTI function is intended to connect the coaxial cable line-driver and receiver path to data-terminal equipment, while the nominal -9 V supply matches older negative-rail interface circuits. The 16-pin through-hole DIP format also suits older instrument and computer hardware that uses socketed or plated-through-hole construction. Before implementing it, confirm the exact pinout, cable termination, connector, and external components in the manufacturer datasheet rather than relying on generic Ethernet transceiver conventions.
おすすめ
Thin Ethernet Network Interface Card
For a legacy network interface card, DP8392CN-1 is relevant where the card exposes a coaxial 10BASE-2 port and already uses the associated negative supply. The 16-terminal DIP package provides a direct through-hole integration path in older computer or industrial controller designs. The key engineering issue is compatibility: the network controller, data bus, isolation requirements, and connector must match the original system. The verified excerpts identify the Ethernet and CTI roles but do not provide timing or signal-level details, so those values require the complete manufacturer document.
おすすめ
Industrial Control-System Retrofit
DP8392CN-1 can be considered for an industrial control or communications chassis that retains a legacy Thin Ethernet interface during a targeted retrofit. The commercial 0°C to 70°C grade and through-hole DIP format may fit equipment-room systems, but the device still requires a -9 V rail and careful signal-integrity review. Do not substitute it into a modern controller simply because both devices are Ethernet-related. Confirm the original schematic, connector pinout, shielding strategy, and required isolation, then validate the complete interface at the cable and system level.
おすすめ
Legacy Coaxial Bus Test Equipment
The device may be useful in test equipment designed to exercise or diagnose an existing coaxial Ethernet node. Its CTI architecture provides the physical-layer interface needed to connect the test fixture to the cable and data-terminal equipment path, while the through-hole package supports repairable fixture construction. The verified data does not specify test-signal amplitudes or timing, so instrumentation limits must be established from the datasheet. In particular, verify that the fixture tolerates the nominal -9 V supply and does not introduce unsafe fault conditions on the legacy bus.
おすすめ
Communications Equipment Restoration
DP8392CN-1 is a plausible candidate when restoring an older communications platform whose schematic calls for a 16-pin coaxial transceiver interface. The verified package and temperature information make it more useful for preservation work than for a new high-speed Ethernet design. Restoration should begin by comparing the original part-number marking, pin table, supply rails, and external network components. Because no verified drop-in alternatives were found, procurement should include a careful manufacturer-datasheet review and, where possible, comparison with known-good hardware.
おすすめ
Educational and Prototype Ethernet Demonstrators
A laboratory or educational system that demonstrates legacy IEEE 802.3 coaxial networking can use DP8392CN-1 to illustrate the physical-layer transceiver role. The 16-pin DIP package is convenient for a visible through-hole prototype or repair trainer, while the -9 V rail makes the power-supply requirements explicit. The demonstration should use a properly isolated and terminated coax setup rather than improvised connections. Since the supplied material does not provide full timing and signal-level values, the instructor should rely on the manufacturer datasheet for safe setup and measurement points.

設計ノート
Design the negative supply around the verified nominal -9 V requirement and verify the manufacturer-defined operating limits before connecting the IC. The supplied excerpts do not provide minimum and maximum supply voltage or current values, so do not infer a generic range. Check bypass-capacitor placement and return-current paths against the original application circuit, especially when the transceiver is used near a long or poorly shielded coaxial cable.
Preserve the 16-pin DIP footprint and verify the exact pin numbering against the manufacturer datasheet before making a replacement board. Through-hole construction is useful for legacy equipment, but mechanical clearance, connector orientation, shield grounding, and cable-entry geometry can be as important as electrical compatibility. A functionally similar Ethernet IC should not be placed on the board until every pin name and supply connection has been compared.
Treat the coaxial side as a controlled physical-layer interface rather than a generic digital bus. Follow the manufacturer application circuit for termination, shielding, grounding, and external protection, because the verified data does not provide impedance, sensitivity, or isolation values. Validate signal levels and timing with the intended 10BASE-2 cable and connector; a successful logic-level test does not prove cable compatibility.
Do not treat DP8392CN-1 as a direct replacement for DS3692 merely because both devices support 10BASE-2. The supplied cross-reference result explicitly states that the DP8392CN-1 is not a pin-for-pin or electrical replacement for DS3692. Also avoid confusing DP8392CN with DP8392CN-1 without checking the order code and datasheet, because temperature-grade and ordering details may differ.
コンプライアンス情報
The verified excerpts identify a commercial 0°C to 70°C through-hole legacy Ethernet interface but do not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification evidence. AEC-Q100 is marked not applicable because the supplied device is not identified as an automotive-qualified component.
