Page 18: Application Information
15. Application information Package parasitics, particularly ground lead inductances and parasitic capacitances, can significantly degrade the frequency response. Since the SA5211 has differential outputs which can feed back signals to the input by parasitic package or board layout capacitances, both peaking and attenuating type frequency response shaping is possible. - Page 19 0.1 F HYST PKDET pin(s).
