DP83816AVNG-TI - 10/100 Ethernet PCI Controller | TI
MPN: DP83816AVNG-TI ✗ Tapus ng BuhayDP83816AVNG-TI Ulas
An Ethernet controller is an interface IC that coordinates data transfer between a host computer or embedded processor and a physical network. The DP83816 belongs to the PCI interface and Ethernet controller hierarchy, where the PCI interface connects to the host bus and the integrated 10/100 Mb/s physical layer connects through twisted-pair cabling. Its integrated design reduces the number of separate interface devices required in a compact network interface design.
The DP83816 supports 10 Mb/s and 100 Mb/s Ethernet operation under IEEE 802.3, while its PCI interface implements the V2.2 33 MHz bus specification. Bus mastering transfers packet descriptors and data directly between the controller and system memory, reducing the processing burden on the host CPU during network traffic. The device also includes power-management support for systems that require controlled low-power behavior.
The 144-LQFP package provides 144 electrical and ground connections needed by the combined MAC, PHY, and PCI functions. Its 20 mm by 20 mm footprint is larger than modern compact Ethernet devices, but it remains practical for conventional PCI motherboards and expansion cards where a large, established controller footprint is acceptable. The package and exposed leads support automated PCB assembly and inspection when board geometry is designed around the specified land pattern.
Typical applications include 10/100 Mb/s PCI motherboards, PCI Ethernet adapter cards, embedded industrial controllers, legacy embedded systems, and PCI-compatible embedded platforms. In each application, the device acts as the network interface between the PCI host and a 10/100BASE-T network, transferring frames through bus-mastered descriptors while the host operating system manages the network stack.
Board design should preserve the PCI signal-integrity topology, provide the required clock and decoupling networks, and route Ethernet pairs according to the manufacturer reference design. Because the controller is a mature PCI device rather than a compact embedded Ethernet interface, designers should confirm host-bus compatibility, software driver support, and connector magnetics before committing the 144-LQFP footprint to a new design.
This page combines the manufacturer’s product information, package identification, interface details, and cross-reference findings into an engineering-oriented view of the DP83816AVNG-TI. It also provides application guidance, drop-in family candidates, and design notes that clarify where the legacy PCI architecture remains appropriate and where a newer Ethernet controller may offer a better system-level fit.

Tipikal na mga Gamit
DP83816AVNG-TI ay nararapat para sa 6 aplikasyons: PCI Desktop Motherboard Networking, PCI Ethernet Expansion Card, Legacy Embedded PCI Platform, Industrial Control Ethernet Connectivity, Network Adapter Retrofit, Embedded Test and Measurement Instrument.
PCI Desktop Motherboard Networking
The DP83816AVNG-TI is well matched to a conventional PCI motherboard requiring 10 Mb/s or 100 Mb/s wired Ethernet. Its V2.2, 33 MHz PCI interface provides a defined host-bus connection, while bus mastering moves packet descriptors and data between the controller and memory with limited CPU involvement. The integrated MAC and PHY reduce the number of interface components required near the rear-panel connector. Designers should follow the manufacturer reference design for PCI routing, clocking, decoupling, and Ethernet magnetics, then validate suspend and resume behavior with the platform firmware.
Inirekomenda
PCI Ethernet Expansion Card
A PCI Ethernet expansion card can use the DP83816AVNG-TI to add 10/100 Mb/s connectivity without implementing separate MAC and PHY devices. The 144-LQFP package provides a clearly defined, high-pin-count footprint, and the bus-mastering architecture supports efficient descriptor and payload transfers. A practical implementation must include the correct PCI interface components, Ethernet transformer or magnetics, line-side protection, LEDs, and a stable reference clock. Signal-integrity review should account for the shared ground plane and keep sensitive clock and Ethernet routes away from high-current switching nodes.
Inirekomenda
Legacy Embedded PCI Platform
The DP83816AVNG-TI fits embedded platforms that retain a V2.2 PCI host bus and require integrated 10/100 Mb/s Ethernet. Its single-chip MAC-and-PHY implementation simplifies the software interface while providing bus-mastered packet movement. This is especially relevant where product longevity and driver stability are more important than a modern small-package footprint. Confirm that the embedded processor or chipset supports the required PCI clocking, transaction model, and power states, and that the operating-system driver supports the controller in the intended target environment.
Inirekomenda
Industrial Control Ethernet Connectivity
An industrial controller can use the DP83816AVNG-TI to connect a PCI-based control system to a 10/100 Mb/s Ethernet network. The integrated physical layer and media access controller provide a complete host-facing network endpoint, while power-management support can assist system-level control of operating states. Because the interface is designed around a 33 MHz PCI bus, the host architecture and driver must support that topology. For deployed equipment, validate network boot behavior, long-duration traffic handling, connector grounding, and cable compatibility with the site infrastructure.
Inirekomenda
Network Adapter Retrofit
The DP83816AVNG-TI is useful for retrofitting wired Ethernet into an established PCI expansion system. Its 10/100 Mb/s support covers legacy 100BASE-TX networks, while the integrated MAC and PHY limit the external circuitry to the supporting network interface and magnetics. Before using it as a replacement, compare the full pin assignment and package drawing with the installed controller, verify supply sequencing and clock requirements, and confirm that the host driver supports the device. This avoids treating a superficially similar Ethernet controller as a direct board-level substitute.
Inirekomenda
Embedded Test and Measurement Instrument
A PCI-based test or measurement instrument can use the DP83816AVNG-TI for management traffic, result transfer, and remote control over a 10/100 Mb/s Ethernet link. The bus-mastering interface can move packet data efficiently, which is useful when transferring logs or configuration files between an instrument and a host computer. The design must preserve the manufacturer’s clocking and reference-network layout, implement suitable Ethernet isolation, and validate throughput and latency under sustained transfers. Legacy PCI availability and operating-system driver support should be checked before selecting this architecture.

Talaan ng Disenyo
Use the manufacturer’s DP83816 reference layout for PCI routing, clock distribution, decoupling, and Ethernet connections. Preserve the documented 144-LQFP land pattern and maintain the specified reference-network values and placement. Keep the 33 MHz PCI clock routing short and isolated from Ethernet magnetics and other switching circuitry. Incorrect clock topology or component placement can cause interface timing and electromagnetic-compatibility problems even when the schematic connections are correct.
Separate and decouple the device’s core and analog supply domains exactly as directed by the manufacturer datasheet. Place the required bulk and high-frequency capacitors at the associated power pins, with short return paths to the ground plane. The available product information does not specify voltage ranges or current limits, so do not select capacitors or power rails by inference. Validate startup sequencing, current margin, and voltage tolerance against the final system power architecture.
Route Ethernet differential pairs as a controlled-impedance pair and keep them continuous over the ground reference plane. Position the Ethernet magnetics and connector to minimize loop area and avoid crossing the pairs with unrelated high-current paths. Differential pair length, spacing, and impedance must be based on the stack-up and connector requirements rather than generic rules. Compliance testing should include the completed board and representative cable lengths.
Do not treat a related Ethernet controller as a pin-compatible replacement merely because both support 10/100 Mb/s Ethernet. Confirm the exact package, pin assignment, supply rails, clock source, host interface, and PHY connections before substitution. Likewise, verify that the host chipset supports the V2.2 33 MHz PCI interface and that an operating-system driver is available. These checks are essential when maintaining a mature PCI platform with a newer controller.
