I am looking for a better understanding of the RFOUT for this part and the matching that is suggested. In the datasheet I have they show 100pF as the DC bi-pass and the AC coupling capacitors. I see other values being used for this part of circuit as well. I understand that it can vary with frequency. We are using the 50 Ohm Output Pull-up technique as described on page 33 of the datasheet. Is there a table or technique for determining the value of these three capacitors and are all three always the same value (whatever the value is determined to be)? We are using a 125 MHz OSCIN to create a 1.9 GHz reference. I believe that the inital value of 10pF may be too small for that frequency. I see 100pF in the evaluation design and other reference designs on your website. I believer we are getting attenuation or return loss from that value. Do you have a recommended method for calculating that value? Let me know. Thank you
