Description
Delphi Engineering Group's ADC3295 is a PMC,
analog to digital converter module designed for
digitizing wide bandwidth analog signals at 10 bits, at
sampling rates of up to 2 Gsps. Buffering of the
digitized data samples is provided onboard. Samples
can be transferred to the host board via the PCI-X
bus at a high rate using the built-in DMA controller.
A Xilinx Virtex 5 FPGA provides continuous sampling,
buffering, and timing. Delphi also offers an FPGA
design kit which allows custom development of the
onboard FPGA. FPGA design can be customized for
specific applications such as digital filtering, data
preprocessing and DSP functions such as FFT.
For systems running Microsoft Windows, Delphi offers
ADCView, a signal visualization application which

configure sampling parameters such as: start/stop
vectors, IRQ operation, and triggering options.
Sample data exportable to analysis applications such
as Matlab.
The ADC3295 is a PMC based technology that has
been rigorously tested to operate on leading
PowerPC, PC, and DSP host processor systems.
Delphi has a proven track-record of delivering highperformance PMC modules for mission-critical
applications.

PCI Interface
Processed sample data is transferred to
the host system through the PCI bus.
Data collection timing and duration are
fully programmable through the PCI bus.
PCI interface is implemented in an
onboard FPGA.
