Installation

In slm.toml add:

microchip-networking = { git = "JITx-Inc/microchip-networking", version = "0.6.4" }

KSZ9563 3 Port Network Switch

circuit

This module defines many of the supporting features for instantiating the KSZ9563 network switch in a design, including:

• Configuration passives
• Test points
• Bypass capacitors
• Power filters
• Crystal resonators

This module makes the underlying component instance netsw public so that the user can directly access ports as necessary.

The current implementation is supports RMII and MIIM for the configuration interface.

  inst netsw : microchip-networking/components/KSZ9563/circuit(substrate)

ports

  port VDD-1v2 : power ; 1.2V Power Rail input. This rail will be used for both the digital and analog 1.2V rails with a ferrite power filter instantiated for the analog.
  port VDD-3v3 : power ; 3.3V Power rail input. THis rail will be used for the VDD-IO and the Analog 3.3V power rail. A ferrite power filter is applied to source to the analog power rail.
  port mii : rmii-bus ; Media Independent Interface implemented as a RMII (Reduced Media Independent Interface)
  port management : miim ; Management interface, currently implemented as a MIIM interface.
  port power-evt-n ; Active low power event signal from the switch
  port irq-n ; Active low interrupt request signal from the switch
  port LEDs : pin[2][2] ; LED1 and LED2 for status signals

Supports

; We have to use a special bundle type that includes the LEDs so the proper LED control pins connected to the right ethernet connector.
require sw-mdi : microchip-networking/components/KSZ9563/MDI-1000BaseT-With-LEDs[2] from netsw.netsw

Parameters

• substrate:Substrate PCB Substrate where the vias are defined. This circuit requires at least one via that is via-in-pad capable.

--

• make-oscillator:True|False Instantiate a crystal oscillator circuit for the switch. Use false here to drive the clock input of the KSZ9563 directly with a logic level signal. Default value is true.
• enable-in-band-mng:True|False Enable the In-band management interface. This allows the user to make modifications to the switch via the ethernet interface. See section 4.10 in the datasheet. By default, this is deactivated.
• enable-on-reset:True|False Enable network switching to start on reset of the network switch. By default this is activated.
• enable-gigabit:True|False Configures Port 3 MAC as Gigabit. If deasserted, then the MAC operates at 100Mbps speed. Default is activated.
• rmii-clock-mode:True|False Configures the RMII directional flow of the clock. In normal mode, the RMII interface receives a clock from the PHY. In clock mode, the RMII interface generates a clock to drive the MAC on a MCU. By default, the clock mode is active. This flag only affects RMII mode.
