Part Number: ADS5527 I'm designing a board that integrate an ADS5527. At the input I've an analog differential signal with no DC component. Looking at the datasheet of the ADCi t seems that the DC component can be provided by the VCM pin of the ADS5527…
Part Number: ADS5527 We realized a board that integrates several ADS5527. At the moment the board does not work well (it seems that the output of the ADCs is always zero). We suspect that the problem is related to the analog input at pins INP and INM…
Other Parts Discussed in Thread: ADS5527 I’ve developed a clock distribution network to feed 60 ADS5527. I’ve used LVDS signal. At the clock distribution network output I’ve obtained the waveform shown in the attached figure. Is this clock waveform acceptable…
Other Parts Discussed in Thread: ADS5527 I'm designigning a clock distribution network to synchronize 60 ADS5527. In the datasheet of ADS5527 I can't find information about the impedance seen at the input of the clock (CLKP and CLKM). Where I can find…
ALB,
Is your EVM a Rev C board? If so I have attached the schematic. Please make sure all jumpers are set per the board photo I am sending. Take a scope probe (diff probe would be better) and monitor the ADC input across R21 and R26. You should see…
Jin,
The schematic looks good for the most part. Please do the following:
1. Install R364 to provide a path to GND.
2. Do not use R361, R362, and R363 wit the ADC_VCM output.
3. Make sure DRVDD and AVDD are 3.3V.
4. Do not need to route ADC_CLKOUTM_F…
Hello Jim,
Apologies for the late reply. I have been traveling and have now just starting to catch up to all the E2E questions.
The revision C of the schematic is attached. The major change on this revision is that we have replaced U15 from a 16-bit…
