Hi,

I am using bit ADC  AD9629BCPZRL7-80 in one of the receiver design.Attached schematic for your reference

 

Inputs to ADC

  • Supply voltage AVDD:1.8V and  DRVDD:3.3V
  • Single ended CMOS 1.8V Clock signal (30MHz) (CMOS 1.8V)
  • SDIO/PDWN pin at Active low (0V)
  • CSB pin at Active High( 3.3V)
  • DFS at Active low (0V)
  • Mode :Non SPI mode
  • ADC analog input :70Mhz

Following output observed :VREF as 1V and VCM as 0.9V

 

Problem observed : None of the ADC digital output bits are toggling.

 

regards,

Shamanth
