ECL based circuit testing

Hi

 

I m using  ADCMP 567 comparator for reducing the base noise of the signal or u can say the data recovery. the PCB is designed at 1Ghz

but the problem i m facing is that in test setup when the input signal frequency is more than 1MHz the shape of the output signal is distorted more like capacitive effect

 

What cud be the possible reason

 

i am using an ECL based IC for the very first time

wat r the requirements for its test setup that differ from TTL

 

regards

uzmeed
