DP83924BVCE - Quad 10 Mb/s Ethernet PHY | Texas Instruments
MPN： DP83924BVCE ✓ 啟用中DP83924BVCE 概覽
An Ethernet physical layer, or PHY, is the interface between a Media Access Controller and physical network media. A PHY converts digital frames and control signals into electrical signaling suitable for a physical layer, while receiving and decoding incoming signals. Within the Ethernet hierarchy, the DP83924BVCE is an Ethernet interface IC, a physical-layer transceiver, a network-interface semiconductor, and ultimately a power-management-dependent mixed-signal component.
The device provides four 10 Mb/s Ethernet ports, on-chip transmit-output filters, and a common four-port twisted-pair transceiver structure. Its 4.75 V minimum and 5.25 V maximum operating supply span supports conventional 5 V equipment designs. According to the manufacturer datasheet, the programmable MAC interface supports most standard seven-signal MAC interfaces, reducing the need for separate physical-layer devices when four network ports share one controller.
The DP83924B architecture organizes the four PHY channels behind a configurable interface to a MAC or repeating-device controller. This multiport arrangement is intended to simplify board-level networking designs while preserving separate twisted-pair channels for each port. Because the available verified material does not enumerate every internal filter, equalization, timing, or link-detection parameter, those values should be taken directly from the current manufacturer datasheet before final signal-integrity or network compliance sign-off.
Typical uses include four-port hubs and repeaters, concentrators, printed-circuit-board Ethernet switches, industrial network interfaces, test equipment, and legacy 10 Mb/s terminal systems. In each case, the quad-port organization is valuable when a controller has enough I/O capacity to service four separate MAC channels and the PCB can accommodate the associated magnetics or twisted-pair network connections.
Designers should pay close attention to 5 V supply decoupling, the 100-pin quad-flat-package footprint, trace routing around each PHY channel, and the external magnetic components required by the implemented network topology. The available data identifies tube packaging and a commercial temperature grade, but it does not provide complete verified dimensions, pin names, absolute maximum ratings, or electrical test conditions.
This page combines the verified distributor and manufacturer-linked specifications with practical integration guidance, package details, application context, pricing caveats, and drop-in replacement analysis. It also distinguishes verified facts from unavailable technical data so procurement and engineering teams can identify the exact information that still requires confirmation from the authoritative DP83924B datasheet.

典型應用
DP83924BVCE 適用於 6 應用s: Four-Port Ethernet Hub and Repeater, Industrial Ethernet Concentrator, Printed-Circuit-Board Ethernet Switch, Legacy 10 Mb/s Terminal Interface, Ethernet Network Test Equipment, Multiport Network Interface Backplane.
Four-Port Ethernet Hub and Repeater
The DP83924BVCE fits four-port hubs and repeaters because one device contains four 10 Mb/s twisted-pair physical-layer channels and a programmable interface for most standard seven-signal MAC interfaces. A hub or repeater controller can therefore service four links through a common physical-layer device instead of four separate single-port PHYs. The trade-off is routing complexity: each channel requires careful PCB layout, appropriate termination and magnetics integration, and verified 10 Mb/s signal integrity. The verified 4.75 V to 5.25 V supply range supports conventional 5 V equipment, while the 100-PQFP footprint demands adequate escape routing and assembly planning.
推薦
Industrial Ethernet Concentrator
The DP83924BVCE can support a concentrated 10 Mb/s Ethernet architecture in industrial terminal or concentrator equipment where four physical-layer links are advantageous. Its four-channel organization can reduce PHY component count and centralize the controller-facing signals through the programmable MAC interface. However, the verified record identifies a commercial temperature grade rather than a quantified industrial temperature range, so deployment conditions must be checked against the manufacturer datasheet. Board designers must also validate isolation, surge requirements, connector strategy, and transformer selection for each port.
推薦
Printed-Circuit-Board Ethernet Switch
The DP83924BVCE is applicable to legacy or dedicated 10 Mb/s printed-circuit-board switching equipment requiring four twisted-pair ports. Its 4TPHY implementation provides a common physical-layer block for a multiport controller, while on-chip transmit-output filters reduce the need for some external filtering. The engineering tradeoff is that four high-speed copper channels in a 100-PQFP package require careful layer-stack selection, return-path continuity, and isolation from surrounding circuitry. Designers should confirm MAC timing, cable-length requirements, and magnetic-component values against the authoritative DP83924B documentation.
推薦
Legacy 10 Mb/s Terminal Interface
The DP83924BVCE can serve multiport legacy Ethernet terminal equipment that operates at 10 Mb/s and needs several twisted-pair interfaces. Its four integrated PHY channels suit equipment with multiple cable attachments and a central MAC or repeating controller. The part is not a general-purpose interface for unrelated serial protocols, so the controller firmware and MAC signaling must conform to the supported seven-signal interface. Mechanical design is centered on the 100-PQFP package, while network performance depends on correct transformer selection, controlled-impedance routing, and validated recovery timing.
推薦
Ethernet Network Test Equipment
The DP83924BVCE is appropriate for test and measurement equipment that must expose several 10 Mb/s copper Ethernet ports to a controller under test. Four PHY channels allow one fixture or instrument to exercise multiple link paths while retaining a common MAC-facing interface. The commercial temperature grade is suitable only where environmental conditions remain within the manufacturer's specified limits, which must be obtained from the datasheet. Instrumentation designs should account for the 5 V supply tolerance, deterministic reset behavior, per-port diagnostics, and the PCB area needed around the 100-lead package.
推薦
Multiport Network Interface Backplane
The DP83924BVCE can support specialized backplane-based networking equipment in which four 10 Mb/s twisted-pair channels share a common controller. Consolidating the physical layers reduces the number of PHY packages compared with four separate devices and provides a defined MAC-interface path. The backplane designer must still establish suitable cable reach, isolation, return paths, and connector architecture because the integrated PHY does not remove the need for external magnetic components. Commercial-grade status and the lack of verified industrial temperature data make this architecture most appropriate for controlled environments unless qualification is completed.

設計說明
Route each twisted-pair channel as a controlled-impedance differential pair from the DP83924BVCE to its network-magnetics interface, and keep the pairs away from noisy power converters and unrelated high-speed clocks. The verified excerpts do not provide the manufacturer's exact trace geometry, so the authoritative DP83924B reference design and layout guidance should govern spacing, pair length, via count, and return-path continuity.
Design the 5 V supply rail to remain inside the verified 4.75 V to 5.25 V range under startup, load, and tolerance conditions. Place local high-frequency decoupling close to the device's supply pins using the values and topology specified by the manufacturer datasheet. Verify ground-return continuity carefully because a multiport PHY can expose small signal-integrity errors as link errors across several channels.
Do not assume that another Ethernet PHY is a drop-in replacement merely because it also supports four ports or uses a 100-lead package. A valid substitution must match the physical footprint, pin-by-pin signal assignment, supply requirements, MAC-interface timing, clocking expectations, and 10 Mb/s transceiver characteristics. No specific equivalent was confirmed by the supplied cross-reference results.
Estimate total device dissipation from the actual 5 V rail current and I/O loading before approving the board layout. The verified excerpts do not provide maximum current, thermal resistance, or junction-temperature ratings, so no thermal calculation is asserted here. Use the manufacturer electrical characteristics and a package-appropriate PCB copper strategy, then confirm temperature rise in the assembled enclosure.
合規資訊
The verified component listing states that the DP83924BVCE contains lead and is not RoHS-compliant. No verified REACH, halogen-free, conflict-minerals, or automotive-qualification data was supplied. AEC-Q100 is marked not applicable because the verified data identifies a commercial-grade network-interface IC and no automotive qualification claim.
