Description

The DP83849IVS/NOPB is TI’s 10/100 Mbps Ethernet PHY transceiver. It provides the physical layer between a MAC (MII/RMII) and a RJ45 Ethernet interface (with magnetics).
Key points:
- Interfaces: supports MII or RMII to the MAC, MDIO/MDC for management.
- Features: auto-negotiation for 10/100 Mbps, 802.3u compatibility, (often) Energy Efficient Ethernet, low-power modes, LED indicators, loopback and fault-detection options.
- Packaging: “VS” indicates a Very Small Outline/VSOP-style package; “NOPB” means Pb-free (lead-free) packaging.
- Applications: embedded Ethernet hosts, microcontroller/SoC-based devices, industrial controllers, gateways, routers, and similar networked systems.
In short, DP83849IVS/NOPB is a compact, Pb-free Ethernet PHY for connecting a MAC to Ethernet, with standard management and low-power options suitable for compact embedded designs.

Features

Key features of DP83849IVS/NOPB:
- 10/100/1000 Mbps Ethernet PHY with full/half‑duplex operation
- Auto-negotiation and 802.3-based link detection (supporting 10BASE-T, 100BASE-TX, 1000BASE-T)
- MAC interfaces: MII, RMII, and RGMII
- MDIO/MDC management interface for register access and PHY control
- Energy Efficient Ethernet (IEEE 802.3az) with low-power/standby modes
- LED outputs for link/activity/speed (configurable)
- Built-in test and loopback modes for diagnostics
- Wake/sleep capability and robust power management
- RoHS-compliant packaging (IVS) with NOPB option
- Wide operating conditions (typical industrial temperature range)
Note: packaging suffixes IVS/NOPB indicate the specific TI package and lead-free option.

Package

DP83849IVS/NOPB uses a 28‑pin VSSOP (Very Small Outline Package), i.e., a lead‑free RoHS package.

Pinout

DP83849IVS/NOPB is a 48-pin Ethernet PHY package. It functions as the physical layer transceiver for 10/100/1000BASE-T (IEEE 802.3) with MAC interfaces (MII/RMII) and MDI connections to the network. The NOPB suffix indicates Pb-free packaging.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal and embedded processing integrated circuits.

Application

- Industrial automation and factory-floor equipment (PLCs, robotics, sensors, motor drives) needing robust 10/100/1000BASE-T Ethernet.
- Embedded networking devices (switches, gateways, IP cameras, routers).
- IoT/edge systems requiring an Ethernet PHY with RMII/MII interfaces.
- Building automation, energy metering and smart-grid equipment for industrial/hars environments (IVS version).

Equivalent

DP83849IVS/NOPB is TI’s 10/100/1000 Ethernet PHY. There isn’t a strict one‑to‑one cross, but common non‑TI equivalents (depending on package/interface) include:
- Marvell 88E1111 (tri‑speed PHY)
- Microchip KSZ9031RN/KSZ9031 (tri‑speed PHY)
- SMSC LAN8720/LAN8742 (10/100 PHYs, usable in some substitutes with constraints)
Note: verify MII/RMII/GMII, voltage, package, timing, and use TI’s cross-reference tool for exact matches.
