KSZ9893RNXI Typical application Circuitry

KSZ9893RNXI

A fully integrated layer 2 managed three-port switch with an optimized bill of materials (BOM) cost for applications with fewer ports and tighter budgets is the KSZ9893RNXI. It's designed and manufactured by Microchip and offers a wide range of features for both managed and unmanaged switch designs.

Features of KSZ9893RNXI:

1. Three-port Switch: The KSZ9893RNXI includes an integrated three-port switch with two 10/100/1000Mbps PHYs and PHY transceivers.

2. Advanced Power Management: This chip offers advanced power management that allows for dynamic power control of PHYs and the switch.

3. Integrated Regulator: The chip features an integrated 3.3V to 1.8V regulator to supply the core power, affording design flexibility.

4. Comprehensive Frame Support: The switch provides comprehensive frame support, including PAUSE frame, VLAN, and QoS.

Application Scenarios for KSZ9893RNXI:

The KSZ9893RNXI is typically used in networking and telecommunication applications like Ethernet switches, routers, and wireless access points. Moreover, it can be found in specialized applications like industrial automation and test equipment.

Detailed Circuit Connection – Ethernet Switch Scenario:

If we were to design a small Ethernet switch using the KSZ9893RNXI, the critical connections would include:

- Pin 2 (VDD33A): This is the chip's 3.3V power supply pin. Connect this pin to your system's 3.3V power source.

- Pin 4 (VDD18A): This pin is the 1.8V power supply pin for the core, which can be supplied by the integrated regulator.

- Pin 19, 20, 22, 23, 26, 27 (TXP/TXN, RXP/RXN): These are the transmit and receive differential pairs for each of the two Ethernet ports. The appropriate Ethernet connectors should be used to link them.

- Pin 1, 3, 24 (GNDA, GNDP, GNDD): These are the ground pins for the analog, digital, and PHY sections. They should be wired to the system ground.

Design Considerations:

1. Power Supplies: Clean power supplies are crucial. You might want to use decoupling capacitors close to the VDD33 and VDD18 pins.

2. Signal Integrity: Ensure the differential pairs are length-matched and have the correct impedance for maintaining proper signal integrity.

3. Grounding: Proper grounding techniques should be implemented, like using a star ground system or a ground plane to avoid ground loops.

In conclusion, the KSZ9893RNXI is a high-performance Ethernet switch IC offering the flexibility and reliability needed in a broad array of network-related applications.
