Forum Post: RE: ADS54J69: ADC is not responding on SDout line
Ryan, That would make sense. The document online for ADS54J69 shows active high powerdown. What document are you looking at in the previous post snippet? Below is from the ADS54J69 datasheet. Thanks,...

Hi Andy, That ringing does look quite severe. My first recommendation would be to remove the pull-ups on all the SPI lines, as they're usually not necessary. Like I mentioned as well, placing a 22 ohm...

Goran, Yes, that seems a bit extreme for phase and amplitude imbalance. I don't think we'll be updating the schematic any time soon but I've taken note of the schematic change request and will see...

Matias, If the serdes rate is 3072Mbps, then serdes/80 will be 38.4MHz. This is the sys clock frequency required if using data width of 64. The transceiver reference clock can be anything that is a...

Hi Ryan, You can use the DAC as a single link or two separate links. This DAC supports up to 4 links but some of the functions only show supporting 2 links. Most cases, I see customers using a single...

Hi Alanderson, Your question: How can I calculate the values when the overvoltage event is coming from a current transformer? In the configuration below, the signal comes from a single line. DL: the...

Hi Chase, I can confirm that sys_clk frequency is twice the one for freerun_clk that I assume is the one going to the free-running clock of the Transceiver Wizard. Now after trying to re-compile, I...

Hi Andy, Thank you for your patience. May I ask why you're sending that first frame of all ones? I don't believe the device requires that, and I wonder if it is not placing the device in an unknown...

Hi Yoshikazu-san, The number in the table 8-5 means how much phase adjustment (the number of tMOD) between channels. When you set the Phase Calibration limit to 0 by programming PHASEn[9:0] =0, it...

Hello Dale-san, Thank you for your quick reply. Now I understand, but the tMOD shown as "PHASE OFFSET RANGE(tMOD)" in table 8-5 is confusing us since it looks as if PHASE OFFSET RANGE = tMOD which can...

Hi DBC, Glad to hear the issue is gone. I'm not too familiar with the DAC121, but you could post a new E2E question for that part and the DAC team will be able to help point out if there are potential...

Hi Zhixiong, 1. There is no required supply sequence. 2. Can you confirm you are able to read or write to the device? For example, can you successfully read the CHIP_ID register (0x02)? We should...

I have 1k resistors in line with all the SPI lines and it is still ringing. I removed the pull-up, but the problem persists. Since my SPI waveform looks the same as the examples in the datasheet, I am...

Hi Stan, Unfortunately not. The ADS809 is a very old Burr-Brown device initially. This was inherited thru the TI acquisition in 2000. Regards, Rob
