  • 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 lacking…

  • RE: AFE7225: LVDS ADC Pin Name/Description Polarity Clarification

    Hi Wayne Cox, Sorry for the delay in my response. I checked with the design team and found that polarity suggested by pin names is correct. Description in Table 2-2 is incorrect. Regards, Vijay

  • 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 this pullup…

  • 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: AUXDAC_A and AUXDAC_B output voltage is not matching with same register configured values

    TI Thinks Resolved
    Part Number: AFE7225 Hi TI Support team, We are configured both AUXDAC_A and AUXDAC_B channels with same external and internal termination resistor values and written same values for both 0x248 and 0x249 registers. But the measured voltage is not…

  • 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 + 4 zeros…

    Thanks for your suggestion, we have sloved this problem.

  • RE: AFE7225: Auxillary DAC output is not proper as per the datasheet.

    Pradeep: I think the missing step is actually loading the desired DAC level into the register. This is done in registers 0x243 and 0x244 (for Aux DACA). The default will be 0. 0xFFF corresponds to a maximum value. Then you have to enable the loaded register…

  • AFE7225: marine VHF wireless transceiver application

    TI Thinks Resolved
    Part Number: AFE7225 Other Parts Discussed in Thread: ADC3224 , DAC3174 , ADS4249 , AFE7070 Hello Guys, Good day. Is AFE7225 applicable for marine VHF wireless transceiver application for marine frequencies from 156 to 162 MHz? Or is there a better alternative…
