Critical Link Announces New Analog I/O Expansion Kit

Syracuse, NY (January 27, 2014) – Critical Link has announced the availability of a new Analog I/O Expansion Kit for the company’s MityDSP-L138F.  The new kit adds three expansion connectors, supporting both low-speed and high-speed digital-to-analog (DAC) and analog-to-digital (ADC) data converters, to the standard MityDSP-L138F Industrial I/O Development Kit. The kit supports both low speed and high speed analog input and output, offering up to 40MSPS high speed input and up to 100MSPS high speed output, including arbitrary waveform generation. The kit was designed for prototyping applications that require data acquisition in addition to on-board signal processing. These include software defined radio (high speed channels), instrumentation, and custom analog measurement and control.

The new expansion kit is compatible with Critical Link’s MityDSP-L138F based development kits (one of which is required to interface with this expansion kit). The expansion board includes:

  • Quad channel 16-bit low-speed DAC
  • Dual channel 14-bit high-speed (options up to 275MSPS) DAC
  • 16 channel low speed (1.8K – 23.7K SPS) ADC
  • 16 bit single channel high speed (80MSPS) ADC
  • 7 External GPIO pins
  • One External I2C bus interface

To speed the development process while utilizing this expansion kit, Critical Link also includes a Linux- based software and firmware SDK, in addition to FPGA source code that can also be used as a reference for a custom implementation.

The MityDSP-L138F System on Module is the highest performance module in the OMAP-L138 family of MityDSPs. The MityDSP-L138F ARM9 system supports QNX, embedded Linux, Windows CE6 and ThreadX operating systems. It features the dual-core OMAP-L138 CPU from Texas Instruments, which provides both an ARM9 applications processor and a C674x Fixed / Floating Point DSP. When combined on the MityDSP with the optional on-board Xilinx Spartan-6 FPGA, system designers have available two 456 MHz CPUs, along with the capability to add fixed function co-processing or I/O co-processing in the FPGA.
