7140 Pentek Dual Multiband Transceiver with FPGA

The Pantek 7140 Dual Multiband Transceiver with FPGA is a software radio transceiver suitable for connection to HF or IF ports of a communications system. It includes two A/D and two D/A converters capable of bandwidths to 40 MHz and above. The Model 7140 uses the popular PMC format and supports the emerging VITA 42 XMC standard with optional switched fabric interfaces. The front end accepts two full scale analog HF or IF inputs on front panel MMCX connectors at +4 dBm into 50 ohms with transformer coupling into AD6645 14-bit 105 MHz A/D converters. The digital outputs are delivered into the Virtex-II Pro FPGA for signal processing or for routing to other module resources.

The Model 7140 complies with the VITA 42.0 XMC specification for carrier boards. This emerging standard provides, among others, for a 4X link with a 3.125 GHz bit clock between the XMC module and the carrier board. With two 4X links, the 7140 achieves 2.5 GB/sec streaming data transfer rate independent of the PCI interface and supports switched fabric protocols such as Serial RapidIO and PCI Express. The Model 7140 includes an industry standard interface fully compliant with PCI 2.2 bus specifications. The interface includes nine separate DMA controllers for efficient transfers to and from the module. Data widths of 32 or 64 bits and data rates of 33 or 66 MHz are supported.
