Hi,
I have question regarding CDCV304 input impedance from customer.
The customer consider what damping register would fit for CDCV304 input 148.5MHz.
CDCV304 input current characteristics is +/-5uA , therefore we can guess that input impedance is roughly 600K-1Mohm.
Would it be possible for you to tell us if the understanding correct ?
In general, dumping resister is estimated by the use of driver output impedance and receiver input impedance (including transmission line).
Would you tell us also the recommended dumping resister value , when customer use SN74LVC1G32DCKR (Vcc=3.2V) as driver for example ?
Best Regards,
Charlie
