Hi, 1) According data sheet of AFE5808 , by default the ADC is capable of generating 14 bit signed 2's complement. It can also be configured to 12 bit. Am i right? 2) I configured the AFE as 16x serialization data rate (3[14:13]=01), 14 bit ADC resolution (4[1]=0), Using TSW1400 for ADC signal capturing and ultrasound echo signal at input then after saving the capture into csv file, I observed the ADC codes are b/w -32768 to 32767 But here my doubt is the range should be b/w -8192 to 8191 for 16x or 14x serialization rate, because the ADC resolution is 14 bit (ADC values are b/w -8192 to 8191). In 16x mode, two 0's are added. How the 14bit ADC data is serially sent out in 16x mode?
