CompactPCI® Serial  Quad PCI Express® Mini Card Carrier Board
Six Antenna Connectors for Wireless Radio Applications (WLAN, WWAN, GNSS)
Additional mSATA SSD Module Socket

The SP4-MAMBO is a peripheral board for CompactPCI® Serial systems and serves as a quad PCI Express® Mini Card carrier, either full- or half-size style. An additional socket is provided for an optional mSATA module. Up to six SMA antenna connectors are available via the front panel, for MIMO operation of wireless Mini Cards, such as WiFi (WLAN) or 4G/LTE (WWAN). Any module socket is wired to an individual Micro SIM card holder.

Each PCI Express® Mini Card socket can accommodate either an USB or PCIe based module. The mSATA socket is suitable for either a SATA SSD, or an USB controlled Mini Card.

The SP4-MAMBO is equipped with an on-board Gen2 PCI Express® packet switch and a PCIe to USB 2.0 bridge, and can be installed into any peripheral slot of a CompactPCI® Serial backplane.



The SP4-MAMBO requires a single PCI Express® lane from the backplane, passed over across the connector P1 to a PCIe Gen2 packet switch (upstream port). The PCIe downstream ports from the switch are used to supply each Mini Card socket with an individual PCI Express® link, as required e.g. by WLAN Mini Cards. Another port from the PCIe packet switch feeds an on-board USB 2.0 controller, which is required for USB type Mini Cards, such as most modems. The related SIM card holders are suitable for 15mm x 12mm Micro SIM cards, which are most widely in use.

Any CompactPCI® Serial peripheral slot - in addition to its PCIe link - may provide a SATA channel and also an USB port, available from the backplane via connector P1. These ports are both routed to the optional on-board mSATA socket (SSD storage module). The SATA Rx/Tx signals are reconditioned by a 6Gbps SATA redriver, for optimum signal integrity. The mSATA connector can be used also with an USB style Mini Card. The associated Micro SIM card holder is positioned below the Mini Card module itself, due to space restrictions on the SP4-MAMBO PCB.
