KSZ8999I Typical application Circuitry

KSZ8999I

The KSZ8999I is a highly integrated device designed for applications that require 10/100 Mbps Ethernet connectivity with integrated switch functionality. Made by Microchip, the KSZ8999I includes nine Ethernet ports, with built-in Physical Layer (PHY) transceivers, and several options for management interfaces. Here's a guideline on how to connect the KSZ8999I in a circuit:

1. Power Supply:Power the KSZ8999I by connecting a stable 3.3V supply to the VDD pins.Ensure that the ground of the circuit is connected to the VSS pins. It is recommended to use bypass capacitors close to these power pins to filter out any possible noise.

2. Ethernet Interfaces:Each of the KSZ8999I's nine Ethernet ports consist of RX and TX pairs. Connect these pairs to the appropriate pins on your RJ45 connectors or another Ethernet interface. Remember to consider transformer coupling for each Ethernet connection, which is often required for signal integrity and electrical isolation.

3. Management Interface:The KSZ8999I can be configured and managed via either an SPI or I2C interface. Connect the SCLK, MOST, MISS, and CS# pins to the corresponding SPI pins on your controller, or SDA and SCL for I2C.

4. PHY Management:The MDC (Management Data Clock) and MDI (Management Data Input/Output) pins are used to control the KSZ8999I's Phys. Connect these to your controller to enable control of the Phys' functionality.

5. Reset and LED Indicators:The KSZ8999I's RESET# pin should be connected to a reset switch or your controller for device resets. The KSZ8999I also provides LED pins to indicate link status, activity, and other conditions. These can be connected to LEDs on your board for easy status visualization.

Be sure to refer to the KSZ8999I's data sheet and reference manual for detailed specifications and wiring guidelines. This will ensure your design meets the requirements of the KSZ8999I and help prevent possible damage to the device.
