DP83816AVNG - 10/100 Mb/s PCI Ethernet Controller | Texas Instruments
MPN: DP83816AVNG ✓ فعالDP83816AVNG جائزہ
An Ethernet media access controller is the system-level component that manages frame transmission, reception, addressing, and host-to-network data movement. In the product hierarchy, the DP83816AVNG is an Ethernet controller, an interface IC, and a PCI networking semiconductor that combines MAC and PHY functions. Integrating these blocks reduces the number of components required by a PC motherboard, PCI adapter card, or embedded PCI networking system.
The device provides 10 Mb/s and 100 Mb/s Ethernet operation and is listed by Texas Instruments as an IEEE 802.3 controller with a 10/100 Base-T/TX PHY and PCI interface. Bus mastering transfers packet descriptors and data directly, reducing the processing burden on the host processor. The cited product information also identifies flexible receive-packet filtration and IEEE 802.3x full-duplex flow-control support.
The DP83816 architecture targets low-cost, high-volume PC motherboards, adapter cards, and embedded systems. Its integrated PCI interface implements the V2.2 33 MHz PCI bus specification for host communication and includes power-management support. Combining the Ethernet MAC and physical layer in one package simplifies board partitioning while retaining bus-mastered packet transfer.
Typical applications include legacy PCI industrial controllers, embedded communication equipment, PCI expansion systems, and host adapter cards requiring 10/100 Mb/s Ethernet connectivity. The DP83816 is particularly relevant to installed industrial systems that retain PCI infrastructure but require a dedicated Ethernet controller rather than a software-only network interface.
Designers should verify the exact pin assignments, signal states, external magnetic-component requirements, reference clock arrangement, and power sequencing directly against the manufacturer datasheet before layout release. The 144-pin LQFP footprint is large, so high-speed trace routing and thermal performance should be reviewed alongside connector placement and magnetics isolation.
This page combines verified manufacturer and distributor information, documented replacement references, package details, and practical sourcing guidance. It also distinguishes confirmed same-footprint order variants from unrelated controllers so engineers do not mistake a functionally similar networking IC for a pin-compatible drop-in replacement.

DP83816AVNG کے لیے موزوں ہے 6 ایپلیکیشنs: Legacy PCI Desktop Network Adapter, Industrial PCI Control System, Embedded PCI Communication Equipment, PC Motherboard Ethernet Connectivity, Network Adapter Card Retrofit, Data Acquisition and Monitoring Node.
Legacy PCI Desktop Network Adapter
The DP83816AVNG fits a legacy PCI expansion card that must connect a host to a 10/100 Mb/s Ethernet network. Its integrated 10/100 Base-T/TX PHY avoids adding a separate physical-layer device, while the V2.2 33 MHz PCI interface supports standard host communication. Bus mastering moves packet descriptors and data directly, reducing CPU involvement compared with a controller that relies on programmed I/O. The 144-LQFP package requires a correspondingly large land pattern, and engineers must still verify clock, isolation, and magnetics requirements from the manufacturer datasheet before fabrication.

Industrial PCI Control System
The DP83816AVNG is suitable for an industrial PCI controller that needs deterministic access to a 10/100 Mb/s Ethernet network without offloading all packet handling to the host processor. Bus mastering transfers packet descriptors and data between system memory and the Ethernet controller, while the integrated MAC and PHY reduce board complexity. The device supports power management and IEEE 802.3x full-duplex flow control. For deployment in harsh industrial equipment, however, the exact operating-temperature grade, supply range, isolation requirements, and EMC design guidance must be checked against the official datasheet before release.

Embedded PCI Communication Equipment
The DP83816AVNG can support embedded equipment that retains a PCI bus while offering a conventional 10 Mb/s or 100 Mb/s Ethernet connection. Its integrated media access controller and physical layer consolidate two major networking functions into one 144-LQFP device. The 33 MHz V2.2 PCI interface and bus-mastered data movement are useful when the embedded host must handle multiple tasks beyond networking. Designers should reserve the footprint, validate the reference clock and power rails, and plan the Ethernet magnetics and signal-path layout according to the manufacturer application guidance.

PC Motherboard Ethernet Connectivity
DP83816AVNG addresses the networking needs of low-cost, high-volume PC motherboards that require a dedicated 10/100 Mb/s Ethernet interface on a PCI bus. Integrating the MAC and PHY reduces the number of networking chips and board interconnects, while bus mastering keeps routine packet transfer away from the host CPU. The part also includes power-management support, which is valuable in systems expected to enter low-power states. Layout planners must provide clean clocking, adequate grounding, controlled Ethernet impedance, and correctly placed magnetics while preserving the 144-LQFP footprint.

Network Adapter Card Retrofit
The DP83816AVNG is applicable to a retrofit or expansion card intended to add 10/100 Mb/s Ethernet connectivity to a PCI-compatible host. The device's integrated MAC, Base-T/TX PHY, and 33 MHz PCI interface provide the essential controller functions in one component, while bus mastering improves throughput from the host perspective. IEEE 802.3x flow control supports full-duplex links, and flexible receive-packet filtration can help organize traffic at the controller. A retrofit should use the official 144-pin land pattern and be validated for connector, magnetics, clock, and power-sequence compatibility.

Data Acquisition and Monitoring Node
A data-acquisition or monitoring node with a PCI host can use DP83816AVNG to provide a 10/100 Mb/s Ethernet management link. The bus-mastering architecture transfers packet data and descriptors without requiring the acquisition processor to execute every network transaction, preserving resources for measurement and control functions. Integrated MAC and PHY functionality shortens the board design compared with a discrete implementation, while receive filtering and full-duplex flow control support managed traffic. Deployment quality still depends on validated thermal performance, isolation strategy, environmental qualification, and an Ethernet layout that meets the manufacturer's recommendations.

ڈیزائن نوٹس
Treat the Ethernet differential pair, reference clock, PCI interface, and power distribution as separate high-priority layout constraints. Follow the manufacturer reference layout for the 144-LQFP footprint rather than generating a land pattern from package dimensions alone. Confirm exposed-pad or thermal requirements, if any, from the official drawing and maintain uninterrupted ground references beneath signal-routing areas.
Verify every supply rail, decoupling value, sequencing condition, and operating-current limit against the Texas Instruments datasheet before schematic release. The supplied excerpts identify 3.3 V through FindIC but do not provide the complete power tree, so 3.3 V should not be treated as confirmation that no other supply or tolerance condition applies. Place high-frequency bypass capacitors at the relevant IC pins using the manufacturer reference layout.
Review the reference-clock and PCI signal paths as potential sources of packet errors or enumeration problems. Use the manufacturer's recommended topology and impedance guidance, minimize stubs, and provide suitable return paths. Ethernet magnetics placement and isolation must also be coordinated with the connector and chassis-ground strategy because poor magnetic-component placement can undermine otherwise correct controller operation.
Do not substitute the DP83816AVNG for another Ethernet controller based only on the shared 10/100 Mb/s function or a similar 144-LQFP outline. The complete pin list, PCI signal definitions, clock requirements, strap settings, and PHY support must match. The verified cross-reference supports DP83816AVNG/NOPB and DP83816AVNG-EX/NOPB as same-family options, but it does not establish pin compatibility for unrelated DP83815 or DP83822 devices.
تعمیل کی معلومات
