DP83846AVHG-NS - 10/100 Ethernet Transceiver | Texas Instruments
料号： DP83846AVHG-NS ✓ 量产中DP83846AVHG-NS 概述
An Ethernet physical-layer transceiver, or PHY, converts logical data into electrical signals suitable for twisted-pair cabling and reconstructs received signals for the digital network controller. The DP83846AVHG-NS belongs to the broader category of Ethernet interface ICs, network interface controllers, and communication semiconductors. A PHY is commonly used when a processor, programmable logic device, industrial controller, or test equipment does not include a compatible Ethernet physical layer.
The verified product information identifies the DP83846AVHG-NS as a single 10/100 Ethernet transceiver in an 80-LQFP (12x12) package. The commercial temperature grade is also identified for the related DP83846AVHG listing. The package provides 80 terminals with gull-wing leads and a square body, allowing the device to be assembled using standard surface-mount PCB processes. The Ethernet capability supports 10 Mb/s and 100 Mb/s network operation, while the exact PHY electrical ratings, media-dependent interface details, and performance limits should be confirmed in the manufacturer datasheet before design release.
Typical applications include industrial Ethernet equipment, embedded control systems, network interface modules, instrumentation, printer controllers, telecommunications equipment, and communication adapters. The 80-LQFP package is particularly appropriate for multilayer PCBs where a high pin count is required to expose separate digital, analog, power, clock, and media-side connections. The package footprint also makes the device suitable for designs migrating from earlier 10/100 Ethernet PHY implementations when the board footprint and functional requirements remain compatible.
When placing this device on a PCB, follow the manufacturer's recommended decoupling, analog-supply layout, clock, reset, and differential-pair routing guidance. Keep the Ethernet magnetics and cable-side routing away from noisy digital and switching-supply paths. Because the exact pin assignments, recommended capacitor values, and supported operating conditions are not stated in the retrieved product snippets, use the official datasheet pin description and application circuit before assigning PCB tracks.
This product page combines the verified package and Ethernet-class information with application guidance, replacement context, and design-oriented selection notes. It is intended to help engineers identify whether the DP83846AVHG-NS matches a required 10/100 Ethernet PHY, commercial-grade 80-LQFP footprint, and surface-mount assembly process.

典型应用
DP83846AVHG-NS 适用于 6 应用s: Embedded Ethernet Controller Interface, Industrial Communication Gateway, Instrumentation and Test Equipment, Printer and Network Adapter, Network Interface Module, Legacy Equipment Retrofit.
Embedded Ethernet Controller Interface
The DP83846AVHG-NS is appropriate when a microcontroller, application processor, or programmable logic device requires a dedicated 10/100 Ethernet physical layer. Place the transceiver between the digital bus or parallel interface of the network controller and the Ethernet magnetics, then route the media-side signals according to the manufacturer reference layout. Its single-port 10 Mb/s and 100 Mb/s support covers both 10BASE-T and 100BASE-TX links without requiring a separate PHY for each supported rate.
推荐
Industrial Communication Gateway
A 10/100 Ethernet PHY provides a practical network interface for industrial gateways that connect sensors, actuators, and legacy equipment to Ethernet backbones. The DP83846AVHG-NS supports 10 Mb/s and 100 Mb/s operation in a square 80-LQFP surface-mount package, which can support dense multilayer gateway designs. Validate industrial temperature, surge, isolation, and grounding requirements separately because the commercial-grade designation and exact electrical limits determine whether additional protection is needed.
推荐
Instrumentation and Test Equipment
The DP83846AVHG-NS can add 10/100 Ethernet connectivity to analyzers, laboratory instruments, and automated test systems that use an external controller for data transfer. A single-port PHY is useful when the host processor already handles upper-layer networking or device management. Keep the PHY clock, analog supply, media-side differential pairs, and magnetics placement consistent with the manufacturer layout to reduce sensitivity to noise and cable-side return loss.
推荐
Printer and Network Adapter
Printers, scanners, appliance controllers, and compact network adapters can use the DP83846AVHG-NS as a dedicated 10/100 Ethernet physical layer. The 80-LQFP footprint exposes a substantial set of power, control, and media connections while remaining compatible with conventional surface-mount assembly. The design must preserve the correct interface voltage levels, clock requirements, and magnetics connection described by the manufacturer datasheet, especially when replacing an existing PHY on a reused PCB.
推荐
Network Interface Module
The DP83846AVHG-NS is suitable for a dedicated network-interface module that exposes a standard 10/100 Ethernet connector while leaving the main board free to handle application processing. Its single-port 10/100 specification matches common legacy and Fast Ethernet infrastructure and can simplify compatibility planning across multiple installed devices. Because the package contains 80 terminals, reserve space for all required supply, ground, control, and media-side connections rather than treating it as a minimal three- or four-pin PHY.
推荐
Legacy Equipment Retrofit
A retrofit assembly can add network connectivity to older equipment by pairing the DP83846AVHG-NS with a compatible host controller and Ethernet magnetics. The 10 Mb/s and 100 Mb/s support is useful for facilities still operating mixed-speed networks, while the 80-LQFP (12x12) package can fit an interface daughterboard. Check the original equipment's connector, isolation, grounding, and environmental requirements, and verify that the complete board footprint remains mechanically unchanged before approving a drop-in replacement.

关键差异点
- Identified single-port 10/100 Ethernet PHY （对比 DP83846AVHG)
- Same 80-LQFP mechanical footprint （对比 DP83846AVHG/NOPB)
- Commercial-grade family context （对比 DP83846AVHG)
设计说明
Use the official DP83846AVHG reference layout for the 80-LQFP footprint, analog-supply connections, grounding, and Ethernet media-side routing. Keep the PHY-to-magnetics differential pairs short, impedance-controlled, and free from test-point stubs. Place the required input, output, and bypass capacitors directly beside their associated pins rather than distributing them around the device.
Separate digital and analog supply paths as directed by the manufacturer datasheet, and provide local high-frequency bypassing at the transceiver pins. Do not infer capacitor values or supply limits from package information; use the official application circuit and electrical characteristics table. Confirm startup, reset sequencing, and power-supply tolerances before enabling the Ethernet interface.
The plain DP83846AVHG, DP83846AVHG/NOPB, and DP83846AVHG-NS suffixes must not be treated as automatically equivalent procurement choices. Compare the manufacturer ordering table, top-mark format, temperature grade, configuration, and shipping-option identifiers. A same-package match alone does not resolve differences in marking, purchasing, or device configuration.
合规信息
The retrieved product information does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the device is an Ethernet interface transceiver rather than an automotive-qualified component.
