  • AFE5401-Q1: How can the AFE5401 be configured so that there are few cycles delay between DSYNC1 and DSYNC2 after the TRIG trigger?

    Resolved
    Part Number: AFE5401-Q1 Tool/software: Hi, How should the AFE5401 be configured so that there are few cycles delay between DSYNC1 and DSYNC2 after the TRIG trigger? This is necessary because the VIP input port of the TDA3x requires a certain time difference…

  • AFE5401-Q1: How to Connect Two AFE5401 Chips to TDA3

    Part Number: AFE5401-Q1 Tool/software: Hi,we are selecting two AFE5401 chips for sampling. The sampled data is output as CMOS data, and then the data is processed by the TDA3. Do we need a CPLD for data conversion between them, or can we directly connect…

  • AFE5401-Q1: Unused PIN

    Part Number: AFE5401-Q1 Tool/software: HI, Please tell me about unused PINs. Normally, I think there is no problem with input PINs being pulled up or down and outputs being OPEN. Are there any recommended methods for handling unused pins for the pins…

  • AFE5401-Q1: IN1_AUX samples corrupted by noise

    Part Number: AFE5401-Q1 Tool/software: Hello, We encounter an issue where while the unit is in operation, the auxiliary channel 1 would start outputting zero (not exactly zero, but close to zero). Power cycling the AFE5401-Q1 will clear the issue and…

  • AFE5401-Q1: GLOBAL_PDN vs PDN_CH1/2/3/4

    Part Number: AFE5401-Q1 Tool/software: Hello, Is the function GLOBAL_PDN same as PDN_CH1, PDN_CH2, PDN_CH3 and PDN_CH4 combined together? Do I get the same effects doing GLOBAL_PDN, compared with doing PDN_CH1, PDN_CH2, PDN_CH3 and PDN_CH4? When I set…

  • AFE5401-Q1: Questions about 100 MSPS Data Processing

    TI Thinks Resolved
    Part Number: AFE5401-Q1 Hi. I have questions about 100 MSPS Data Processing. I'm curious about how AFE5401 processes data when it has maximum sampling rate. As far as I know, if it is 25 MSPS per Channel, the period of output data is 100 MHz. Since…

  • AFE5401-Q1: The range of values output is strange.

    Resolved
    Part Number: AFE5401-Q1 Hi. The data output from the AFE5401 comes out strangely. The array data type is uint16_t. If you look at the screenshots, there are moments when the numbers are gradually decreasing and then going from 2 to 4068. It looks like…

  • AFE5401-Q1: Questions about DCLK in AFE5401

    Part Number: AFE5401-Q1 hi. I have a question about DCLK of AFE5401. Is DCLK is unconditionally output when a clock is input to the chip? I'm inputting 25 MHz clock into the chip, but dclk is outputting 3.3v and the waveform doesn't occur. I would…
