Product details
Overview
DP83816AVNG/63SN from Texas Instruments is a single-chip 10/100 Mb/s PCI Ethernet MAC and integrated physical layer (PHY) in a 144-pin LQFP package. It implements IEEE 802.3-compliant MAC, PCI V2.2 bus interface, and full-duplex 10/100BASE-TX/T transceivers with auto-negotiation, supporting embedded systems and PC motherboard designs requiring low-power 3.3-V operation and Wake-on-LAN functionality.
For engineers reviewing the DP83816AVNG/63SN datasheet, DP83816AVNG/63SN pinout, DP83816AVNG/63SN application, or DP83816AVNG/63SN equivalent, key selection considerations include its integrated MacPhyter-II™ architecture, 25-MHz reference clock requirement, 2KB TX/RX FIFOs, MII interface support for external PHYs, and EEPROM-based configuration loading at power-on.
Technical Context
The DP83816AVNG/63SN integrates a PCI bus master interface compliant with PC97–PC99 and ACPI v1.0, enabling burst transfers up to 128 dwords and reducing CPU overhead via descriptor-driven DMA. Its internal PHY supports both 10BASE-T and 100BASE-TX with adaptive equalization, baseline wander compensation, and ANSI X3.263 TP-PMD compliance.
Configuration is loaded from serial EEPROM at power-on using MA3/EEDI, MA4/EECLK, and MD4/EEDO pins; the CFGDISN pin allows disabling this feature. The device supports VLAN tagging, long frame handling (>1518 bytes), and flexible packet filtering including perfect unicast match with MSb masking, 512-entry hash tables, and deep pattern matching for up to four unique byte sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10/100 Mb/s PCI Ethernet controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTL8139C(L) | Realtek 32-bit PCI 10/100 MAC+PHY; lacks MII interface, no WoL ARP/pattern match, higher typical IDD (160 mA) | Targeted at ultra-low-cost consumer PC boards; limited power management and diagnostic features | Choose RTL8139C(L) only if cost is primary constraint and WoL granularity or MII flexibility is unnecessary |
| Intel 82559ER | Intel 32-bit PCI 10/100 controller with enhanced security features, TCO watchdog, and deeper power states (D3cold) | Designed for enterprise client platforms requiring AMT and vPro compatibility | Choose Intel 82559ER when platform-level manageability, secure boot, or extended lifecycle support is required |
Compared with DP83816AVNG/63SN, RTL8139C(L) offers lower BOM cost but sacrifices WoL precision and MII extensibility, while Intel 82559ER adds enterprise manageability at higher cost and power - DP83816AVNG/63SN uniquely balances PCI99 compliance, integrated PHY performance, and EEPROM-configurable flexibility for industrial and legacy embedded use cases.

FAQ
What is the reference clock requirement for DP83816AVNG/63SN?
The DP83816AVNG/63SN requires a precise 25-MHz ±50 ppm clock source connected to the X1 pin. It supports either a 25-MHz crystal across X1/X2 or a CMOS-level oscillator on X1 only. This clock drives both MAC timing and PHY data recovery, and deviation beyond ±50 ppm may cause 100BASE-TX link instability or auto-negotiation failure. The DP83816AVNG/63SN does not synthesize or multiply this clock internally.
Does DP83816AVNG/63SN support external PHY devices via MII?
Yes, DP83816AVNG/63SN supports external PHY connection through its Media Independent Interface (MII), configurable via the EXT_PHY bit in the CFG register. When enabled, MDIO/MDC, TXD[3:0], RXD[3:0], TXEN, RXDV, CRS, COL, and TXCLK/RXCLK signals become active for interfacing with standards-compliant 10/100 PHYs. The DP83816AVNG/63SN retains full MAC functionality and descriptor-based DMA in this mode.
How does DP83816AVNG/63SN handle Wake-on-LAN events?
DP83816AVNG/63SN supports five WoL trigger types: Directed Packets, Magic Packet™, ARP Requests, Pattern Match (up to four user-defined byte sequences), and PHY Status Change. It achieves 297 mW standby power in WoL mode and asserts PMEN# to signal power management events. Configuration is stored in external EEPROM and loaded at power-on, allowing persistent WoL enable/disable and pattern definitions without host software intervention.
What package and thermal characteristics apply to DP83816AVNG/63SN?
DP83816AVNG/63SN uses a 144-pin LQFP (PGE) package measuring 20.00 mm × 20.00 mm with 0.5-mm pitch. Its thermal resistance is RθJA = 47.2°C/W, RθJC(top) = 10.5°C/W, and RθJB = 28.3°C/W. The device operates from 0°C to 70°C ambient and requires standard PCB copper pour under the exposed thermal pad for reliable heat dissipation in continuous 100-Mb/s operation.
Can DP83816AVNG/63SN operate in both 10BASE-T and 100BASE-TX modes simultaneously?
No, DP83816AVNG/63SN operates in one speed mode at a time - either 10BASE-T or 100BASE-TX - determined by auto-negotiation result or forced configuration. Its single differential TX/RX pair (TPTDP/TPTDM and TPRDP/TPRDM) is reconfigured dynamically: 10BASE-T uses Manchester encoding with 2.2–2.8 Vpp differential swing, while 100BASE-TX uses MLT-3 with 0.95–1.05 Vpp and strict jitter limits (≤1.4 ns). Simultaneous dual-speed operation is not supported.
