Teledyne SP Devices Presents ADQ32 and ADQ33

TeledyneTeledyne SP Devices has released the ADQ32 and ADQ33 — a fourth-generation modular data acquisition boards optimized for high-throughput applications. The combination of on-board open field-programmable gate array (FPGA) and high-speed data streaming makes them ideal even for the most computationally demanding applications.

The dual-channel 12-bit digitizers support synchronous sampling at 2.5 gigasamples per second (GS/s) per channel for ADQ32 and 1 GS/s per channel for ADQ33 and feature an open Xilinx Kintex Ultrascale KU040 field-programmable gate array (FPGA). The digitizers are streamlined for high-volume applications and are therefore suitable for integration by original equipment manufacturers (OEMs) in areas such as swept-source optical coherence tomography (SS-OCT), time-of-flight mass spectrometry (ToF MS), and distributed optical fiber sensing (DOFS). ADQ33 is not export-controlled and therefore does not require any license.

Custom application-specific digital signal processing (DSP) can be performed in real-time in the on-board FPGA to characterize signals and extract valuable information. It can also be used to perform data reduction so that the output rate matches the 7 Gbyte/s sustained transfer capacity of the PCI Express interface. The data can then be post-processed either on the central processing unit (CPU) of the host PC, or transferred via peer-to-peer to a graphics processing unit (GPU).

This architecture offers great flexibility and allows the designer to use the most suitable type of processing resource for a given task. Examples of application-specific DSP include fast-Fourier transform (FFT) and k-space remapping for SS-OCT, and waveform averaging and zero suppression for ToF MS.

In addition to the high streaming rate and computational flexibility, the ADQ32 also offers excellent analog performance in terms of the effective number of bits (ENOB), spurious-free dynamic range (SFDR), and more. Hardware trigger, selection of internal/external clock, and general-purpose input/output (GPIO) simplify system-level integration.
