  • ADC12J2700: What creates the biasing voltage of the JESD pins of the ADC12J2700?

    Resolved
    Part Number: ADC12J2700 Hello. Can someone tell me what instantiates the biasing of the JESD pins? These are the DS [7:0]_P and DS [7:0]_N pins of the device. Is the biasing established automatically on powerup or is it a result of some SPI command? …

  • ADC12J2700: CAL_STAT bit 2 toggling

    Resolved
    Part Number: ADC12J2700 We are seeing bit 2 in the CAL_STAT register (0x5b) toggle occasionally if we poll that register repeatedly. We're operating with background calibration enabled, and generally read a value of 0x09 from the register, but 30-50%…

  • ADC12J2700: SYSREF delay calibration

    TI Thinks Resolved
    Part Number: ADC12J2700 We're using an ADC12J2700 with a continuously running SYSREF. To date we've just been using the default RDEL value, but we're seeing some board-to-board (and possible temperature related?) variations where we see the "Dirty capture…

  • ADC12J2700: Reg 0x006 Datasheet Question

    Resolved
    Part Number: ADC12J2700 Hello, My customer is using ADC12J2700. To confirm configuration I/O operation, they read the following register values: Reg 0x003 (Chip type): 0x03 (expect 0x03) Reg 0x006 (Chip version): 0x03 (expect 0x13) Reg 0x00C-D (Vendor…

  • ADC12J2700: Should the ADC12J2700 have spurs at 1/2 and 1/4 of the sampling frequency?

    TI Thinks Resolved
    Part Number: ADC12J2700 Hello We are using the ADC12J2700 in our prototype. Anyhow we took a long capture from the ADC and we noticed that we can see Spurious products of the ADC sampling frequency in the data. Is this normal??? We are seeing 1/2 and…

  • RE: ADC12J2700 JESD204B setting ???

    Resolved
    Hi Stephen I would compare all of the detailed signals at the FMC connector. Something must be different between the ADC EVM and your DAQ module in terms of location, signal level, etc. I don't have that information from your board, so I don't know exactly…
