1. USB-C connector
2. Pull-downs for CC1 and CC2
3. ESD protection diodes for the USB2 data bus.
4. Shield termination

inst usb-if : connectors/components/USB/USBTypeC/USBC-HighSpeed-Iface()

Ports

USB : usb-data
VDD-USB : power

Parameters

• R-query: Resistor query parameters - default is get-default-resistor-query().
• C-query: Capacitor query parameters - default is get-default-capacitor-query().

Weidmuller terminal block

This is a parametric component modeling the Weidmuller LSF-SMT family of terminal blocks.

inst terminal-block : connectors/components/LSF-SMT/component(num-poles = 3)

Ports

p : pin[num-poles]

Parameters

• num-poles : Int - the number of poles in the terminal block

RJ45 Ethernet jack

RJ45 Module

This is a Pulse Electronics JD0-0001NL, wrapped in a module to map it to standard ports for MDI, and the LED, shield and tap pins. The user is expected to use a require statement to extract the 1000Base-T or 100Base-T interface for their application.

inst ethernet-jack : connectors/components/JD0-0001NL/connector

Ports

  port CT       ; Device-Side Center Tap
  port ISO-CT   ; Isolated Cable-Side Center Tap
  port SHIELD
  ; Status LEDs
  port LED-G : polarized-ca
  port LED-Y : polarized-ca

Supports:

MDI-100Base-TX
MDI-1000Base-TX

PCIe Edge Connector

Edge-Conn-PCIe Component

This is a parameterized edge connector for PCIe which is configurable from x1 to x16 lanes. The connector supports the PCIe protocol which is defined in JSL (https://docs.jitx.com/reference/jsl/protocols/pcie.html?h=). The user is expected to instantiate this connector with an argument defining the PCIe lane width. Options for the lane width are:

PCIe-x1
PCIe-x4
PCIe-x8
PCIe-x16

inst pcie-edge : connectors/components/PCIe/Edge-Conn-PCIe(PCIe-x16) ; for a x16 lane connector

Ports

  port pcie : pcie(width, PCIe-PRSNT#) ; PCIe port with the specified width and presence detect
  port smbus : std-smbus() ; standard SMBus port
  port jtag : jtag ; standard JTAG port (`TRST` is supported via the reset port)
  port reset : reset ; reset port

Power Pins

  p+12V
  p+3_3V
  p3_3Vaux
  GND

M.2 Edge Connector

M2-2280-ADAPTER Module

This is a parameterized edge connector for a 2280 M.2 edge connector which is configurable with support for B and/or M type connectors (at present). The connector supports the PCIe (https://docs.jitx.com/reference/jsl/protocols/pcie.html) or SATA (https://docs.jitx.com/reference/jsl/protocols/sata.html) protocol. The user is expected to instantiate this connector with an argument defining the connector type. Options for the type are (including the no key option first):

[]
[M2-B-TYPE]
[M2-M-TYPE]
[M2-B-TYPE M2-M-TYPE]

inst m2-2280-adapter : connectors/components/M2-2280-ADAPTER/module([M2-B-TYPE])

Ports

  port vdd3v3 : power

This port definition enables connectivity to 3.3V power as defined by the interface standard.

Supported Protocols

Once instantiated, the connector will be available with the appropriate protocol enabled for the user to access. To enable the use of a specific protocol, the user must instantiate the connector with the appropriate type (for instance, instantiating a B-type connector allows either SATA or pcie(2)) to be used. Note that the SATA protocol and pcie(x) protocols are mutually exclusive. The following protocols are supported:

Supports

  pcie(2)
  pcie(4)
  SATA

In order to use one of these protocols, the user should utilize a require statement like one of the following (all are mutually exclusive):

  require sata : SATA from m2-2280-adapter
  require pcie : pcie(2) from m2-2280-adapter
  require pcie : pcie(4) from m2-2280-adapter

Board Outline

The M.2 form factor supported in this library is the 2280 form factor (22.0 mm x 80.0 mm). The geometric outline of the connector with key positions is defined in the following variables:

M2-default-board-shape
M2-board-shape-B
M2-board-shape-M
M2-board-shape-B-M

The user can use these variables to create a custom board outline for their application.

; define the board with both a B and M key
val board-shape = M2-board-shape-B-M
set-board(an-example-board(board-shape))

Note that there is a grounded mounting hole at the center top of the board as well. Use the PTH mounting hole from the mechanical repo (https://github.com/JITx-Inc/mechanical) to create this mounting hole.

  inst G1 : pth-mounting-hole(
    PlatedHole(
      hole = Circle(1.750),
      copper = Circle(2.750)
      mask = 0.2,
    ))
  place(G1) at loc(0.0, 80.0) on Top
  net (G1.p[1] GND)
