SDR-4000 WM
Wireless Modem for Software Defined Radio Applications

The SDR-4000 Wireless Modem (WM) supports black-side (IF-to-Ethernet) digitization and processing of complex waveforms. It consists of an XMC-3321 dual transceiver module mounted onto a 3U PRO-4600 carrier card. Each SDR-4000 WM provides modem, link and network layer processing of a software defined radio.

The PRO-4600 and XMC-3321 have been architected to support waveforms requiring low latency deterministic operation to maintain synchronization of the frequency-hopped Tactical MILCOM network. This is accomplished by placing control on a PCI bus that is separate from the data path. High-speed data is transferred from the XMC-3321 to the PRO-4600 over an ANSI VITA 42.0 XMC interface.

The SDR-4000 WM is available in either an air-cooled or conduction-cooled configuration and supports two IF input channels, two IF output channels, an internal or external 10 MHz reference and high speed sample clock, Gigabit Ethernet, RS232 and JTAG connectivity. The SDR-4000 WM employs a combination of two Xilinx Virtex-4 FPGAs, a TMS320C6416T DSP and an MPC8541E General Purpose Processor.
