: Configure initial PHY address and operating modes using pull-up/pull-down resistors on "strap-in" pins during power-up. PCB Layout
You can find the comprehensive technical specifications for these transceivers on the Microchip Technology website . Key datasheets include: KSZ8081MNX/RNB Data Sheet ksz80 ob s4lv02 datasheet
The host processor communicates with the KSZ8081 via the MDIO/MDC serial interface. This allows the host to read link status, speed, and duplex, or to write configuration changes. : Configure initial PHY address and operating modes
While is not a valid datasheet keyword, it strongly suggests a two-chip solution : WiFi + Ethernet gateway modules) combine:
Some embedded modules (e.g., WiFi + Ethernet gateway modules) combine:
