Data Translation Inc. has announced the availability of the DT9841 Fulcrum II Series of data acquisition modules that combine Texas Instruments' floating-point TMS3206711 DSP with the speed of two 24-bit sigma-delta ADC and DAC on a standard 6U card that communicates to the host via USB 2.0.

The Fulcrum II Series builds on the company's Fulcrum I technology and can be used in embedded applications for vibration, signal analysis, and test and measurement.

The module is equipped with eight simultaneous channels of 24-bit sigma-delta ADC and two simultaneous 24-bit sigma-delta DAC, both of which are capable of performing up to 100kSa/s. The DT9841 also has 24 lines of digital I/O and up to three counter timers with up/down capability.

Each ADC and DAC subsystem has its own high-speed pathway in and out of memory, enabling them to execute real-time measurements without processor intervention. The embedded C6711 DSP is software-programmable and can be used in a standalone or system test operation. It also comes with 2MB of Flash memory for autonomous operation.

Tools include host software to allow users to install and configure the module from the host, tools for downloading and executing DSP programs, an API for writing host programs to communicate with running DSP programs, an API for building utilities and diagnostics, and sample programs that use the two APIs. In addition, users can develop programs in TI's Code Composer Studio IDE.

The board comes in two memory configurations: the DT9841-128 with 128MB of SDRAM and the DT9841-64/2 with 64MB of SDRAM and 2MB of Flash.
