Configurable digital down-conversion (DDC) channels with custom digital signal processing (DSP) and continuous data transfer capabilities.
Linköping, Sweden, October 25, 2019 - Teledyne SP Devices, a business unit of Teledyne Technologies Incorporated (NYSE: TDY), today announced the release of the ADQ7WB, a dual-channel 12-bit wideband digitizer with 6.5 GHz analog input bandwidth and 5 giga-sample per second (GSPS) sampling rate per channel. The wide instantaneous bandwidth and unprecedented dynamic performance combined with customizable real-time digital signal processing (DSP) and high data transfer rates makes it an ideal platform for satellite communication systems, radar, 5G, and more.
Direct RF Sampling and Multi-Band Support
ADQ7WB allows for direct sampling and transfer of intermediate frequency (IF) or radio frequency (RF) signals with up to 1 GHz instantaneous bandwidth within the frequency range 1 MHz to 6.5 GHz. This approach results in improved noise performance and lower cost as external mixers and local oscillators (LOs) are not needed. The intuitive digital down-converter firmware option can be configured to separate up to four individual IF/RF sub-bands and convert them to baseband for subsequent processing. One example of use is in Global Navigation Satellite System (GNSS) receivers which typically use three sub-bands with different center frequencies.
Optimized for Data Streaming and Computational Performance
In addition to the real-time onboard signal processing capabilities, ADQ7WB also supports continuous data streaming to the host PC or GPU. The GPU peer-to-peer streaming with rates of up to 7 Gbyte/s offers great flexibility to implement real-time signal processing either in the FPGA, GPU, or both. For spectrum monitoring applications, functions such as advanced frequency trigger can be implemented in the FPGA while the GPU is used for computationally intensive processing such as fast Fourier transforms (FFTs) with extreme resolution bandwidth. For applications requiring offline analysis, for example synthetic aperture radar (SAR) or spectrum recording, ADQ7WB also supports high-speed streaming to disk storage.
Dynamic Range Advantage
Teledyne SP Devices' products feature proprietary digital performance-enhancement technology that provides industry-leading spurious-free dynamic range (SFDR) performance. The ADX real-time error-correction IP operates in the background to remove unwanted performance-degrading artifacts in time-interleaved analog-to-digital converters (TIADCs). Time-interleaving is commonly used in many of today's ADCs and the built-in error-correction is often insufficient. ADX provides system-level performance beyond ADC datasheet specifications and therefore results in competitive advantages for our customers.
