Tuning the MAX2607 EV Kit for High Differential Voltage
The differential output voltage on the MAX2607 EV Kit can be measured using a differential probe. But due to board parasitics and the input capacitance of the probe, using passive pullups, the swing was only 320mVP-P. The solution is to use inductive pullups that resonate out those capacitances. This new application delivers 2400mVP-P differential VOUT when measured with a differential probe on a spectrum analyzer. This application note details the modifications made to the board, as well as some theory behind the calculations.
