  • AFE7900: NCO Phase Accumulator Reset after Freq Change

    Part Number: AFE7900 Hi is there an option to reset the NCO phase accumulator after frequency hopping was done? (using the same NCO)

  • AFE7900: Regarding the compensation of phase imbalance between channels of AFE7900

    TI Thinks Resolved
    Part Number: AFE7900 Tool/software: Hello support team, We have designed a custom AFE7900 board with identical front end chain for each individual ADC channels ( Channel A, Channel B, Channel C, Channel D). Each channel is having frequency range of…

  • AFE7900: Unexpected behaviour of RX channel in system mode 3.

    Part Number: AFE7900 Currently working on the AFE7900, where two receive channels are being used in system mode 3. Each channel uses two lanes with a sampling rate of 184.32 MHz. Channel 1 has an NCO set to 120 MHz, and Channel 2 has an NCO set to 415…

  • AFE7900: About AFE7900 config question
