Microchip 32-Pin QFN Ethernet Transceiver KSZ8091RNBCA 3.3 V 100 Mbps RMII 10Base-T 100Base-TX

Microchip KSZ8091RNBCA is a high-performance 32-pin QFN Ethernet transceiver designed for reliable 10Base-T and 100Base-TX physical layer networking applications. Operating at a 3.3 V single supply, it transmits and receives data over standard CAT-5 unshielded twisted pair cables, supporting a maximum data rate of 100 Mbps with RMII (Reduced Media Independent Interface) compliance version 1.2. The device measures compactly at 4mm length, width, and height in a surface-mounted QFN package which is ideal for space-constrained PCB layouts.

This transceiver provides essential features such as an MDC/MDIO management interface for flexible PHY register configuration and programmable interrupt outputs to enhance network diagnostics. It also includes LED link and activity status indicators for easy monitoring. Integrated on-chip termination resistors maintain signal integrity over differential pairs, while baseline wander correction helps maintain data accuracy.

The KSZ8091RNBCA supports HP Auto MDI/MDI-X functionality, enabling the reliable detection and automatic correction of cable types, eliminating user errors during installation. Its auto-negotiation capability dynamically selects the highest link speed between connected devices ensuring optimized network performance.

Designed to operate reliably between 0°C and 70°C, this Ethernet transceiver is lead-free and complies with RoHS standards, suitable for industrial and commercial network applications requiring robust physical layer connectivity. Typical use cases include embedded systems, networking devices, industrial automation, and communication modules integrating Ethernet capabilities.
