KSZ9897RTXC Typical application Circuitry

KSZ9897RTXC

The KSZ9897RTXC is a sophisticated seven-port switch integrated circuit (IC), designed and fabricated by Microchip Technology. It is developed with advanced features aimed at both managed and unmanaged switch designs, which allows a range of applications.

KSZ9897RTXC Feature Set:

1. Seven-Port Switch: The KSZ9897RTXC incorporates a fully integrated seven-port switch with five 10/100/1000Mbps PHYs and GMII/RGMII/MII/RMII interfaces.

2. Energy Efficiency: The chip integrates Energy Efficient Ethernet (IEEE 802.3az) for reduced power consumption during periods of low data activity.

3. Quality of Service: The KSZ9897RTXC supports quality of service (QoS) with 4 priority queues per port, and IEEE 802.1p/IPv4/IPv6 packet prioritization.

4. Security Features: Enhanced security is provided by support for 802.1X port-based authentication.

KSZ9897RTXC Application Scenarios:

This switch IC is typically employed in scenarios such as network interface cards (NIC), Ethernet-based multimedia systems, digital TVs, set-top boxes, and NAS devices, among others. It's a versatile component that meets diverse networking requirements.

Detailed Circuit Connection – Ethernet Switch Example:

For designing an Ethernet switch using the KSZ9897RTXC, critical connections would include:

- Pin 26, 27, 29, 30, 36, 37, 40, 41, 45, 46 (RXP0/RXN0, RXP1/RXN1, RXP2/RXN2, RXP3/RXN3, RXP4/RXN4): These are the receive differential pairs for five of the Ethernet ports. Connect these pins to their respective Ethernet connectors receive pins.

- Pin 28, 31, 35, 42, 44 (TXP0/TXN0, TXP1/TXN1, TXP2/TXN2, TXP3/TXN3, TXP4/TXN4): These are the transmit differential pairs for the Ethernet ports. They should be linked to their corresponding Ethernet connector's transmit pins.

- Pin 25 (VDD33P0): This pin is the 3.3V power supply pin for the PHY. It should be tied to a 3.3V power supply.

- Pin 2 (VDDA33): This is the analog 3.3V power supply pin, which should be connected to a 3.3V power source.

- Pin 7 (GNDA): In analog circuits, this pin serves as the ground. It should be attached to the system's ground plane.

Design Considerations:

1. Power Supplies: Providing clean power supply sources is crucial. For stability, decoupling capacitors ought to be positioned adjacent to the VDD33 and VDDA33 pins.

2. Layout: To maintain signal integrity, differential pairs should be length-matched and should have controlled impedance.

3. Grounding: Implementing proper grounding techniques can help to avoid ground loops and other interference issues.

In a nutshell, the KSZ9897RTXC is a powerful, feature-rich Ethernet switch IC that offers a high degree of flexibility and efficiency, making it suitable for a wide range of networking applications.
