Product Description
Microchip KSZ8091RNAIA-TR is a highly integrated single-supply Ethernet physical-layer transceiver designed for 10Base-T and 100Base-TX applications. It operates with a maximum supply voltage of 3.3 V and supports data rates up to 100 Mbps, delivering reliable transmission and reception of data over standard CAT-5 unshielded twisted pair cabling.
This transceiver implements the IEEE 802.3 standard, making it suitable for a wide range of Ethernet interface designs in industrial, manufacturing, and commercial network equipment. The device is packaged in a compact 24-pin QFN form factor measuring 4 mm by 4 mm with a height of 1 mm, facilitating high-density PCB integration.
Its integrated features include on-chip termination resistors for differential pairs, a built-in 1.2 V low-noise regulator to supply the core, and flexible digital interfaces compatible with 1.8 V, 2.5 V, and 3.3 V logic levels. Wake-on-LAN functionality supports multiple detection methods to initiate device wake-up with minimal power consumption.
Power-saving and power-down modes are incorporated to reduce energy usage when the transceiver is idle, contributing to greener designs. The supply current is approximately 47 mA during operation, making it suitable for energy-conscious applications.
The KSZ8091RNAIA-TR is ideal for use in electronic components, networking equipment, embedded Ethernet interfaces, industrial automation, and communication modules requiring robust physical layer connectivity. Its high integration reduces board costs and simplifies layout complexity.
Single-supply Ethernet PHY compliant with IEEE 802.3 for 10Base-T/100Base-TX. On-chip termination resistors and internal 1.2 V regulator for enhanced integration. Wake-on-LAN functionality with flexible detection schemes.
