Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The KSZ8081RNACA is a single-supply 10Base-T/100Base-TX Ethernet physical layer (PHY) transceiver for data transmission and reception over standard CAT-5 unshielded twisted pair (UTP) cable. It is a highly integrated PHY solution featuring on-chip termination resistors and an integrated low-noise regulator for 1.2V core power supply, providing 1.8/2.5/3.3V digital I/O interface support.

KSZ8081RNACA Features

Interface Support: Provides a simplified media-independent interface (RMII) that can be directly connected to the MAC of Ethernet processors and switches (RMII compliant).

Auto-negotiation: Automatically selects the highest link speed (10/100 Mbps) and duplex mode (half/full).  

Low-power mode: Supports power-down and power-saving modes.  

Diagnostic functions: Features LinkMD TDR cable diagnostic functionality to identify faulty copper cables.  

High integration: On-chip termination resistors and low-noise regulators reduce the need for external components, lowering costs and simplifying PCB layout.
