Instructions for KSZ8993M

1. Power Supply Configuration:

   • Connect the VCC pin to a stable supply voltage within the operating voltage range.
   • Ensure that bypass capacitors are placed close to the VCC and GND pins to stabilize the power supply.

2. Signal Integrity:

   • Use controlled impedance PCB traces for differential pairs to maintain signal integrity.
   • Keep the length of the differential pairs as short as possible to minimize noise.

3. ESD Protection:

   • Place ESD protection devices at the interface connectors to protect against electrostatic discharge.

4. LED Connections:

   • Connect the LED pins to appropriate current-limiting resistors and LEDs for link/activity indication.

5. Auto-MDI/MDIX:

   • No configuration is required; the device automatically detects and corrects crossover connections.

6. Sleep Mode:

   • To enter sleep mode, assert the sleep control signal. The device will reduce power consumption significantly.

7. Wake-on-LAN:

   • Configure the device to monitor for specific wake-up patterns during sleep mode to enable wake-on-LAN functionality.

8. Configuration and Management:

   • Use the MII/RMII interface for configuring and managing the device through software.

Note: Always refer to the official datasheet and application notes for detailed specifications and advanced configurations.
