Crowd Supply XYNC Octo is a low-cost MIMO (Multiple-Input and Multiple-Output) SDR (Software Defined Radio) platform, designed for situations or use cases that involve a large band of spectrum monitoring or massive MIMO systems. The XYNC Octo is essentially a motherboard for connecting XTRX boards together, resulting in a multi-channel SDR.
The XYNC Octo comes equipped with eight removable XTRX boards, metal installation brackets, cables for all of the TX/RX ports and the GPS port, and a special board for synchronizing the XTRX units. Each onboard XTRX provides two transmit channels and two receive channels. Thus, The XYNC Octo offers eight transmit channels at 30.0MHz to 3.7GHz, and eight receive channels at 1.8GHz to 6.0GHz. Two XYNC Octo boards can be connected together to increase the number of RX/TX channels, or to increase throughput per channel. Connecting more than two XYNC boards is also possible, but requires an external clock and 1pps signal distribution circuitry.
On the digital side, each XTRX unit is connected to a PCIe switch that multiplexes the XTRX PCIe lanes into a single PCIe 2.0 x4 connector.
