PCIe dual digitizer for DSP
Eletter Product
The DRX16 is a mezzanine board that pairs with a PCIe main board to simultaneously digitize two IF signals, at the same rate or different rates, via two ports with 16-bit ADCs.
Custom FPGA-based DSP designs are available. Alternatively, for basic signal capture and spectral display, standard EDT firmware and software are included.
The board has a configurable Xilinx Virtex 6 LX FPGA (XC6VLX240T) and two identical ports for 2 to 300 MHz. The ports can be filled with two no-gain input direct modules (IDX, option A), or two fixed-gain input direct modules (IDX-FG, option B) with the same or different gain settings.
Each port has its own 16-bit ADC. Output is digitized by the ADCs and captured in the FPGA, which performs DSP or routes data to the main board.
Each port has a sample clock that can be tuned independently from 10 to 130 MHz. A third clock is available via the sample clock I/O connector, which can be set as input or output.
The timebase can be the provided 10 MHz TCXO, or a user-provided source linked to the reference input. A reference output and a time code input (1 pps or IRIG-B) also are included.
The main board supplies DMA, plus additional memory and programmable FPGA resources.
