Detection Threshold. Reference DC current threshold for input signal power detection. Data output Out[k] is
muted when the power of the equalized version of In[k] falls below the threshold. Tie to ground to disable
electrical idle preservation and always enable the limiting amplifier.
Equalizer 1 differential input, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 4GHz
frequency response is recommended.
Power supply. 1.2V supply voltage. The use of parallel 100pF and 10nF decoupling capacitors to ground is
recommended for each of these pins for broad high-frequency noise suppression.
Equalizer 2 differential input, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 4GHz
frequency response is recommended.
Equalizer 3 differential input, CML. The use of 100nF low ESL/ESR MLCC capacitor with at least 4GHz
frequency response is recommended.
