The Reduced Media Independent Interface reduces pin counts between the MAC (Microcontroller/Processor) and the PHY. It operates using a synchronous 50 MHz reference clock. Pin Number (32-QFN) Description Transmit Data Bit 1 2 Transmit Data Bit 0 3 Transmit Enable from MAC 7 Receive Data Bit 1 8 Receive Data Bit 0 10 RX_ER / ISO Receive Error / Isolation Config 11 Carrier Sense / Receive Data Valid 14 Input/Output 50 MHz Synchronous Reference Clock 2. MII Mode (KSZ8081MNX Variant)
The KSZ8081/41 series provides a low-power, small-footprint physical layer interface for Fast Ethernet applications. It translates digital MAC data into differential analog signals to drive standard copper network cables.

This board typically requires professional installation using an LED Panel bonding machine (specifically for COF punching). It is not considered a user-replaceable part without specialized industrial equipment.
: Incorporates on-chip differential pair termination resistors. This design eliminates external pull-ups, simplifying PCB layout and reducing trace reflections. The Reduced Media Independent Interface reduces pin counts
Identifies the core family line (KSZ80xx series 10/100 Ethernet PHY).
: Supports communication with downstream Media Access Controllers (MACs) using variable digital I/O rail tolerances including 1.8V, 2.5V, and 3.3V . MII Mode (KSZ8081MNX Variant) The KSZ8081/41 series provides
: Uses the standard MII (Media Independent Interface).
Originally developed by Micrel and now a part of , the KSZ80xx series is widely used in applications ranging from industrial controls to automotive systems for its high level of integration and diagnostic capabilities.
