  • AFE7225: Additional Registers

    Part Number: AFE7225 Tool/software: Hello, I've noticed that in some other forum messages that there are registers that are not detailed in the data sheet. Is there a set of additional registers that are not published in the datasheet that you can provide…

  • AFE7225: EVM SPI Programming

    TI Thinks Resolved
    Part Number: AFE7225 Tool/software: Hello, I wanted to purchase the AFE7225EVM board. It appears that the SPI interface is mainly manipulated via a GUI. I wanted to write custom SPI commands in software to send to the chip. This would allow me to test…

  • AFE7225: Differential Clock Input Level

    TI Thinks Resolved
    Part Number: AFE7225 Tool/software: I was looking through SLOA229 ("Working with DC coupled Clock pins in AFE7225") and saw that it was mentioned that the VCM buffer on the chip may not come up if the input signal is not large enough in amplitude…

  • AFE7225: DAC Powerdown Output Compliance

    Part Number: AFE7225 Tool/software: Hello, I have been going through the design of the AFE7225 into my system and was wondering if the stated output voltage compliance is valid when the DACs are powered down (through register 0x207). I have been planning…

    Thanks for your suggestion, we have sloved this problem.

  • AFE7225: CMOS straight offset binary TX/RX?

    Part Number: AFE7225 The docs cover DFS_RX and DFS_TX which seem limited to LVDS-only (DFS_TX is in 5.7 - LVDX TX INPUT INTERFACE REGISTERS, and DFS_RX is in 5.8 - LVDS RX OUTPUT INTERFACE REGISTERS). Is there a CMOS equivalent? The documentation is…

  • AFE7225: AFE7225: What is the expected impedance of each AFE DAC output pins

    TI Thinks Resolved
    Part Number: AFE7225 Hi, As per the current sync DAC requirement, We have given 71.5 ohm pullup to P5V0 and 165 ohm pull-down to ground to maintain 50ohm impedance in AFE DAC output (IOUTP/N_A_DAC and IOUTP/N_B_DAC). In assembled board, Due to…

  • AFE7225: Can 160MHz BW signal be handled by AFE7225? _ Continued

    TI Thinks Resolved
    Part Number: AFE7225 Hi, In recent post I asked if AFE7225 can handle 160MHz signal. The answer was "if it is instantaneous bandwidth of 160MHz, ii can not" Here my application is 160MHz is the IQ data(I+, I-, Q+, Q-) coming from RF down converter…

  • AFE7225: Can 160MHz BW signal be handled by AFE7225?

    Resolved
    Part Number: AFE7225 Other Parts Discussed in Thread: AFE7700 Hi, I have baseband TX and RX signals with BW up to 160MHz, can AFE7225 handle them from ADC/DAC bandwidth point of view? THanks, Tiejun

  • AFE7225: SPI Word Width

    TI Thinks Resolved
    Part Number: AFE7225 Hi All, I want to configure AFE7225 with python spidev (it sends 8 bit per transaction). AFE7225 has 12 bit wide address and 8 bit wide data. Would AFE work properly if I send 24 bits to the chip via spidev (12 addr + 8 data…
