  • AFE7901: Impedance matching

    Resolved
    Part Number: AFE7901 Tool/software: Hi, I'm a little bit confused. The datasheet says that the impedance of the TX port is a differential 100 ohm, but in some application notes and the layout I can see the impedance is a differential of 50 ohm. In the…

  • AFE7901: ADC Ramp test pattern appears on A and B channels when enabled only on A

    Part Number: AFE7901 Tool/software: I am using CAFE79xx_V2p5 lib to configure and enable ADC ramp test pattern. When I set topno=0 and chno=0, ramp test pattern appears on both A and B channels instead only on A. Is this expected behavior? Attaching latte…

  • AFE7901: Change Nyquist band (and RX frequency) after device bringup sequence

    Resolved
    Part Number: AFE7901 Other Parts Discussed in Thread: AFE7950 Tool/software: Hi, We are using the AFE7901 on a custom board and are trying to change the RX NCO frequency at runtime (after boot) with the updateRxNco function. This operations fails for…

  • AFE7901: Strong signal effects the NSD

    Resolved
    Part Number: AFE7901 Tool/software: as we can see in the datasheet the NSD rises up when the input signal increases can you explain this phenomenon ? I assumed it is the multiplication between the high input signal and the sampling clock and what…

  • AFE7901: Input impedance vs Frquency

    TI Thinks Resolved
    Part Number: AFE7901 Other Parts Discussed in Thread: AFE7900 Tool/software: Hi, I'm willing to use the AFE from 400 - 6000MHz with the same port so I'm dealing with wideband impedance matching. I'm looking for a measurement \ documentation of the input…
