Hi,
I have a two signals whose frequency is 100-200Mhz
i picked ADC which has DDR LVDS interface and sampling rate 500MSPS with 12bit width and dual channel, and importantly stock availablity which is ADS5407
Can any one guide me how to use the ADC ADS5407 for below things
1. protection :
At maximum my signal will swing between -1V to +1V ,but there is a chance of +2v and -2v in worst cases, how to protect ADC from this worst cases situation
2. reading negative values:
my signal is of two channels, each channel swings in range of -2v to +2v, absolute maximum
in such case if i need to read negative going pulse what should be my Vcm ?
i assume the adc can read between 0-Vref only , kindly help how to understand and read negative going signal
