  • ADS5295: Frame clock shifted at higher frequencies

    Resolved
    Part Number: ADS5295 Hello I am running the ADS5295 in 10-bit single wire mode. At ~4 MSPS, I read the test patterns properly (as set in registers 25H, 26H, and 27H). At higher speeds (~16 MSPS) the data that I read is shifted by 1 or 2 bits. I tried…

  • ADS5295: 10x mode while controlling the LCLK PHASE

    Resolved
    Part Number: ADS5295 Hello, In the datasheet, Fig. 71, in the 10x mode the rising edge of the ADCLK sometimes occurs when DDR LCLK is low, and sometimes when DDR LCLK is high. Which makes sense due to the 2.5x clock ratios. The confusing part is in Fig…

  • ADS5295: How can we use it in single-ended mode without a transformer/amplifier

    Resolved
    Part Number: ADS5295 Hello, Our input signal's BW is below 10 MHz. but we need high sampling frequency (up to 100 MHz). If we use the one of the differential inputs as single-ended, and connect the other to Vcom, what do we lose?

  • ADS5295: Global power down modes

    TI Thinks Resolved
    Part Number: ADS5295 Dear Team, 1.Does the ADS5295 has two power down modes ? Standby and Global power down ? How is it possible to enable each one of them ? 2. Does the device need to be re-configured after Standby or Global power down ? 3. What is…

  • ADS5295: Bad Test Pattern On A Signle Channel

    Part Number: ADS5295 Hi, We are using ADS5295 in one of our systems. In a few units we encountered some abnormities. We are using the ADS5295 test patterns for a word alignment calibration during system start-up. We set registers 25h and 26h for a test…

  • ADS5295: ADS5295 Power Gating

    Resolved
    Part Number: ADS5295 Will this device have power supply issues such as noise or startup difficulty when power gated with a high side switch, provided the switch has adequate drive, rise time, etc?

  • ADS5295: Question about ads5295 14x capture mode.

    Resolved
    Part Number: ADS5295 Hi. I already posted several question about ADS5295. But I'm asking because there's still something I'm not sure about. Q1. when I set 14x serialization mode and disable filter (like averaging..), where does two zero bit…

  • ADS5295: Is it possible to synchronize two ADS5295 in two-wire mode?

    TI Thinks Resolved
    Part Number: ADS5295 Hi. We have two ADS5295 in two-wire mode with the same input clock. The frame clocks, generated by chips, are 1/2 of input clock. Often, after the start, these two ADCs are not synchronized - the second generates frame clock shifted…

  • ADS5295: About test pattern & sync pattern.

    TI Thinks Resolved
    Part Number: ADS5295 I am using ADS5295 and I have some questions about the ADC's test pattern.! Q1. On page 48 of the datasheet, Setting register 45h , D1=1 enables sync pattern mode. The datasheet does not mention the sync pattern. Does this…
