Note1:
It is recommended that a by-pass capacitor of 0.01uF value be placed between pin #6 and pin #3 and an AC-coupling
capacitor of the same value be placed in series with pin#4 for optimal performance. For ASTX, please connect pin #1 and
#3 to GND.
Note2:
Pin#2 and Pin#5 should be left floating (No Connect = N.C.)
