概述

Description

KSZ8041RNL-TR is a standalone 10/100 Mbps Ethernet PHY transceiver from Microchip (Micrel). It provides the physical layer between an Ethernet MAC and an RJ-45 with external magnetics, enabling 10BASE-T/100BASE-TX operation with auto-negotiation and auto-MDIX. The MAC side connects to the controller via MII or RMII, while management is done through MDIO/MDC. Key features include full/half duplex support, link status indicators, and low-power modes. The “-TR” suffix indicates Tape & Reel packaging for SMT assembly. Typical use is to add Ethernet capability to a microcontroller or SoC that lacks a built-in PHY, in embedded, industrial, or consumer designs. For exact pinout, interface mode, voltage ranges, and recommended external components (magnetics, decoupling, and LED connections), consult the KSZ8041RNL datasheet.

Features

KSZ8041RNL-TR features (concise):
- 10/100BASE-TX Ethernet PHY (IEEE 802.3 / 802.3u)
- Auto-negotiation for speed and duplex (10/100 Mbps, full/half duplex)
- Auto MDI/MDI-X (auto-crossover)
- MAC interfaces: RMII and MII compatibility
- LED outputs for Link, Activity, and Speed
- External 25 MHz reference clock input
- Single-supply operation with low-power/power-down modes
- Requires external magnetics (RJ45/magnetic jack)
Note: This is a PHY device; magnetics and MAC are external.

Package

KSZ8041RNL-TR uses a 28‑pin QFN package (5x5 mm), RoHS lead-free, in Tape & Reel packaging.

Pinout

- Pin count: 28 pins (28-pin package).
- Function: 10/100 Mbps Ethernet PHY (Physical Layer Transceiver).
- MAC interface: selectable MII/ RMII to the MAC core.
- PHY side: MDI interface to RJ45/magnetics.
- Management: MDC/MDIO for PHY registers.
- Clock: REFCLK input (for RMII).
- Control: RESET_n input.
- LEDs: two LED outputs for link/activity.
- Power: VDD and GND pins.
- Packaging: TR = Tape & Reel.

Manufacturer

What kind of company: A global American semiconductor company that designs and manufactures embedded microcontrollers, analog/mixed-signal ICs, memory, and interface devices such as Ethernet PHYs; publicly traded on NASDAQ (MCHP).

Application

Typical application areas for KSZ8041RNL-TR include:
- Embedded/MCU-based designs needing a 10/100 Ethernet PHY
- Industrial automation and control networks
- Consumer networking gear (routers, switches, access points)
- IP cameras and video surveillance
- Network printers and POS terminals
- OEM/development boards requiring RMII/MII Ethernet PHY interface

Equivalent

Common equivalents (10/100BASE‑TX PHYs with RMII/MII):
- Texas Instruments DP83848C/DP83848V
- TI LAN8720A
- TI LAN8740A
- TI LAN8742A
Note: verify pinout, voltage, and interface mode (MII/RMII) for any drop‑in substitute; packaging (TR) affects only the package, not core functionality. Cross‑refs may include similar Microchip/KSZ PHYs (e.g., KSZ8081/KSZ8041 family).
