• Optional firmware package for the onboard FPGA
  • ADX corrects TI-ADC offset, gain and phase errors so that unwanted image spurs does not limit achievable SFDR.
  • FW2DDC contains two digital downconverters (DDCs) consisting of quadrature mixers and decimation filters that help reduce the data rate, improve the signal-to-noise (SNR) ratio for the band of interest, and translate the RF frequency to an intermediate frequency (IF) for baseband processing.
  • The subsequent finite impulse response (FIR) filters can be used either for further noise reduction, for channel equalization, or for correcting in-phase and quadrature (IQ) imbalance.
  • Firmware updates can be done by the user via the ADQUpdater tool that is included in the SDK

FW2DDC equips ADQ7WB and ADQ7DC with real-time functions commonly used in radio frequency (RF) receivers. It also contains the proprietary ADX technology which corrects mismatch errors in time-interleaved analog-to-digital converters (TI-ADCs) and thereby ensure industry-leading spurious-free dynamic range (SFDR). The digital signal processing also helps reduce the data rate to a manageable level in order to simplify data post-processing and storage.
