The invention relates to a hydrocracking catalyst containing: a hydrogenative component which is selected from at least one group VIB metal, at least one group VIII metal and combinations of same; at least one matrix comprising at least one oxide which is selected from an amorphous oxide, an oxide with low crystallinity and a mixture of both; and at least one microporous crystalline solid material which, in the calcined and anhydrous state, has molar composition X2O3:nYO2:mZO2, wherein X is a trivalent element, Y is at least one tetravalent element that is different from Ge and Z is Ge, and which, im the calcined and anhydrous state, has an X-ray diffractogram containing at least diffraction lines with d values=13.64, 7.87, 4.82, 4.55, 4.11 and 3.41 Å. The invention also relates to the method of preparing the inventive catalyst and to the use of same in hydrocarbon hydrocracking processses.
