ADS8519 TIMING SYNCHRONIZATION FOR 32 CHANNEL SIGNAL.

Other Parts Discussed in Thread: ADS8519

Hello,

I need support for ADS8519 data converter Part ,Please find my questions in below:

1.I am using 32 channel adc signal which use the part of ADS8519, with internal clock reference 9 mHZ .This 32 channel signal is control through FPGA.

When i give the sampling input signal (common for all 32 channel) and give control signal to start the 32 channel ADC at a time through FPGA.

I could find all 32 channel does not synchoronize.The data which i recieve is not even and also some channels the datas are update with previous sample.

So, There is a mismatch in timing in between 32 channels.

Please help me to sort out this issues.

Thanks in advance !

Regards,
Mohamed Sidiq.H

  • Hi Mohamed

    If you can provide block level representation of how ADS8519 is used in 32 channel system, that would be helpful. If you can attach part of schematic which includes ADS8519 and FPGA interface section that would help me understand your setup clearly.

    Thanks & Regards
