Part Number: ONET2804T

dear:

      one of our customer need used ONET2804T on 100G Rosa, have to questions :

     1. for the filter capacitor: 

in the datasheet, It is recommended to use two single layer ceramic (SLC) capacitors in the range of 270 pF to 680
pF for power supply decoupling.   

     the range is 270~680, my question is which is the best value of the capacitors ?

     2. SCL and SDA pin , these two pins must to reserved of can not used, Thanks 

  • 1. 680p better, but some 680p capacitors do not have as accurate high frequency performance as 270p capacitors do.
    2. I do not understand. Can you rephrase?
