High-speed digitizer boasts open FPGA architecture

High-speed data acquisition is made simple with a 12-bit digitizer that offers up to 10 GSPS sampling rate and 2 Gbyte/s sustained data transfer to a host PC. Teledyne’s ADQ3-series digitizer provides high-performance data acquisition in a compact, standalone USB 3.2 form factor.

Digitizers—crucial in analytical and sensing systems such as automated test equipment (ATE), distributed fiber optic sensing platforms, LiDARs, mass spectrometers, and swept-source optical coherence tomography—are undergoing a transformation amid growing demand for faster data acquisition. It inevitably calls for higher resolution, faster imaging speeds, and more granular real-time analysis.

That’s because new use cases in sensing systems generate gigabytes of data per second, demanding efficient real-time processing and high-speed data transfer. Then there is the issue of preserving signal integrity in compact and noise-sensitive environments, which mandates compact form factors that can be placed close to the detector within the system enclosure.

ADQ3-USB, housed in a robust, fanless enclosure, allows engineers to place the digitizer close to the detector. This also minimizes cable length and reduces signal reflections, a crucial factor for optimizing analog performance in high-speed applications.

ADQ3-USB features onboard FPGA capabilities for real-time signal processing. That enables it to support continuous data streaming at up to 2 Gbyte/s via USB 3.2. Moreover, even large volumes of raw data up to 20 Gbyte/s can be efficiently reduced and transferred without bottlenecks.

Next, it eliminates the need for PCIe slots, leading to fast and simple integration with mini-PCs and laptops. This also makes it suitable for mobile setups, embedded systems, and OEM applications.

ADQ3-USB’s open FPGA architecture also allows design engineers to implement application-specific algorithms directly on the 1/2 digitizer. That, in turn, reduces the need for post-processing and enables real-time decision-making.

Finally, this digitizer supports multiple firmware packages tailored to specific application needs. That includes FWDAQ for standard data acquisition, FWATD for waveform averaging, FWPD for pulse detection, and DEVDAQ for custom FPGA development.
