Product description
This 64 bit PCI-X card provides wide-bandwidth data capturing capability with
its on-board 14bit 80MSPS (AD9245) analog to digital converters with up to
320MHz analog input bandwidth. The on-board FIFO sample memory is able to store
262Kword of captured data for each channel. The data can be forwarded through a
PCI bus by a master mode DMA capable PCI controller (PCI9656, 66MHz 32/64 bit),
or dedicated IO ports can be used for direct connection to DSP units. External
clocking and triggering possibilities are provided.
Besides the input channels the card contains two output channels too. Before the
14bit 80MSPS (AD9744) digital to analog conversion, the data is stored in the
FIFO memory with 262Kword capacity. The out data buffer could be filled through
the PCI bus or using the dedicated IO ports.
The analog input/output conversions use the same sampling clock for in-phase
operation and could be triggered together.

Product description
DRU-304A is a multifunctional analog input card with 4 ADC channels. The output
data stream of ADCs is processed by digital down converter (DDC) chips (AD6624),
which are able to tune their 16 digital channels anywhere into the frequency
pass band and down convert the signal to a base band domain. The 16 out channels
of the down converters fed into the FPGA for further processing. From the FPGA
it is possible to forward the data through the PCI bus or using the dedicated IO
ports directly to a DSP unit. The down converters could be programmed through
PCI.
This multifunctional receiver board combines high-speed analog to digital
conversion with digital processing suitable for multi channel
wide-and/narrow-band/phase-array down conversion and filtering.
