 The ADACMaster III is a LYRIO add-on module designed for Lyrtech’s SignalMaster Dual and SignalMaster Quad. The ADACMaster III is a phase-synchronous, dual-channel, ADC/DAC module designed to bring new levels of performance and flexibility to a wide variety of signal processing applications including advanced telecommunications, software-defined radio, testing and measurement, medical applications, and more. Such data-intensive applications benefit from the module’s two 14-bit ADCs capable of sampling at up to 125 MSPS; the dual-channel 16-bit, 500-MSPS interpolating DAC; and the optimised system synchronisation. The ADACMaster III is also equipped with one onboard Virtex-4 FPGA (LX25 or SX35) that allows the module to preprocess incoming data before it is transferred to the LYRIO+/LYRIO carrier board (post-processing from the carrier board is also possible). The Virtex-4 FPGA is capable of delivering up to 96 GMACS of FPGA-based digital signal processing power—unrivalled might at your fingertips.
Combining the ADACMaster III with the DSP–FPGA processing engines of the SignalMaster Dual and SignalMaster Quad yields a complete and very-high-performance IF/baseband solution.
The ADACMaster III comes with a complete board software development kit that makes it easy to design and test complex algorithms. It is also possible to simultaneously design and test in a real-time environment through the module’s integration to the model-based design software tools for Simulink.
Features and Benefits
- Benefits from optimised system synchronisation coding, processing, and sound generation.
- Excellent between-channel and external noise insulation (up to –100 dBc inter-channel crosstalk insulation)
- Two 14-bit, 125-MSPS input channels
- Two 16-bit, 500-MSPS output channels
- Multiple clock sources—two external clock inputs (ADC and DAC), onboard synthesizer (optional external reference), and tight clock synchronization circuit
- A Xilinx LX25 or SX35 Virtex-4 FPGA that offers unsurpassed capabilities and high-performance logic
- An onboard flash PROM that simplifies booting the FPGA
- An array of tools that allows designing complex algorithms for the ADACMaster III such as block models with the popular MATLAB and Simulink programs
- The ADACMaster III is also compatible with one of the most powerful integrated development environments on the market—ISE Foundation
- A GPIO-32 port with 32-bit user I/O header routed to the onboard FPGA
- Independent, software-programmable gain amplifier/attenuator on each acquisition/transmission channel (with the exception of the DC-coupled option for the input channels only, which have a fixed unity gain)
Applications
- Software-defined radio
- Advanced base stations
- 2×2 smart antennas, multichannel IF systems
- Cable modem termination systems
- Radar and sonar
- GPS anti-jamming receivers
- High-speed testing and measurement systems
