  • Page 10: Pex 8624-Aa Rdk Hardware Architecture

    PEX 8624-AA RDK PCI Express Interfaces The PEX 8624-AA RDK is designed around the PEX 8624, a 6-port, 24-lane Gen 2 switch, and is based on the form factor specified in the PCI Express CEM 2.0 Specification. The PEX 8624-AA RDK offers five PCI Express (PCIe) interfaces: a x8 PCI Express Card Edge connector (P1), three x16 PCI Express Edge Card connectors (SLOT 1, SLOT 2, &...

  • Page 11: Configuration Modules And Receptacle Cm1

    Configuration Module Receptacle CM1 is a 200-pin high-speed Mezzanine Connector. It is soldered on the PCB of PEX 8624-AA RDK. It directly connects to lane 4 to lane 7 of the PEX 8624, lane 4 to lane 7 of PCI Express card edge connector P1, lane 0 to lane 3 of PCI Express Edge Card Connector SLOT 2, and lane 0 to lane 3 of 4x mini-SAS connector IP1.

  • Page 12: Pci Express Card Edge Connector P1

    CM1 receptacle, the PEX 8624’s lanes 4-7 are routed to Connector P1 and become the upper four lanes of Port 0’s x8 link. By default, the PEX 8624-AA RDK sets this port to be the upstream port. Connector P1 also provides 12V and 3.3V power, along with PERST# and REFCLK_P/N to the RDK.

  • Page 13: Reference Clock Circuitry

    Figure 2-3. Use mini-SAS Connector for NT Function Setup Reference Clock Circuitry The PEX 8624-AA RDK reference clock circuitry contains a one-to-four differential clock fan out buffer (U2) from SpectraLinear (CY28400-2). The clock fan out buffer supports four 100 MHz PCI Express reference clocks with the option for constant frequency and spread spectrum outputs.

  • Page 14: Reset Circuitry

    Hot-Plug capable through the use of the I2C bus and external I/O expander devices. The PEX 8624-AA RDK implements Hot-Plug control circuitry for SLOT 1 and SLOT 2. SLOT 1 uses the on-chip parallel Hot-Plug controller while SLOT 2 uses the Serial Hot-Plug control capability through the I2C and I/O expander.

  • Page 15: Serial Hot-Plug Controller Circuits

    Serial Hot-Plug Controller Circuits PEX 8624-AA RDK also implements the serial hot-plug controller circuitry to PCI Express SLOT 2. By default, the RDK is configured to bypass the serial hot-plug controller. In order to configure port 1 at PCI Express SLOT 2 as a Serial Hot-Plug port with the port 0 is still a x4 upstream port, use the EEPROM to write 2’b00 to the bit [14:13]...

    PCI Express connector SLOT 2. Serial EEPROM The PEX 8624-AA RDK contains an 8-pin DIP socket for a serial EEPROM (U17). The board is populated with a blank On Semi CAT25080LI-G 32-Kbit device. The CAT25080LI-G device can directly interface to the PEX8624.

  • Page 17: Power Distribution

    Power Distribution The PEX 8624-AA RDK has two sources of DC power. The first source is the card edge connector (P1). The x8 connector provides up to 2.1A at 12V and 3.0A at 3.3V from the PCI Express edge card connector it plugs in. The power from P1 is intended to power the PEX 8624, PCI Express connector SLOT 2, and the on-board electronic components.

  • Page 18: Port Link Status Indication (D17 - D22)

    Port Link Status Indication (D17 – D22) The PEX 8624-AA RDK provides up to six green color link status LEDs, D17 to D22, to indicate its port 0, 1, 5, 6, 8 and 9 link states. LED on, off, and three blinking patterns cover all five states of port link status. (See...
