Rincon Research Corporation’s (RRC) P2A family is becoming deprecated. It uses multi-rate signal processing techniques to combine up to six digital IF packet streams into each frequency-multiplexed DAC output. The P2A system can include up to four X7D2285 cards. Each card contains two 10GbE inputs, a Xilinx Virtex 7 FPGA, and two DACs. Therefore, the P2A can combine up to 48 digital packet streams into eight DAC outputs. Optional RF splitters may be included in the chassis to split DAC outputs for signal distribution to multiple modems or other devices.

The P2A system can also include X6A1250 ADC cards to add digital L-band software-defined radio (DLSR) functionality. Refer to DLSR2 for more information. P2A systems can accommodate up to four cards total.

The compact 19 inch rackmount (1U) chassis contains the RF components required for connecting directly to L-band analog modems, block up converters, or a signal distribution infrastructure. The integrated, high-performance cavity filter provides a spectrally-clean L-band output from 950 MHz to 1750 MHz.

The 10 Gigabit Ethernet (10GbE) SDDS inputs feed a flexible de-packetizer that can be configured to receive multicast or unicast data from multiple sources across multiple VLANs. The P2A supports both 40 MHz and 80 MHz bandwidth signals.

The P2A’s large network buffer feature provides uninterrupted data playback even with large network latency. The configurable network buffer also enables the P2A to generate long periods of continuous data even with non-coherent reference clocks.

Built upon high-performance FPGA technology, the P2A supports seamless in-field firmware upgrades to meet the demands of evolving requirements. RRC’s scalable solution makes it easy to deploy and maintain hundreds of units.
