manufacturer: description:note: 1. the level to be set on fs is determined by the nominal operating frequency of the vco. the vco frequency (fnom) always appears at nq and nq outputs when they are operated in their undivided modes. the frequency appearing at the ref[1:0] and ref[1:0] /vref[1:0] and fb and fb/vref2 inputs will be fnom when the qfb and qfb are undivided and ds[1:0] = mm. the frequency of ref[1:0] and ref[1:0] /vref[1:0] and fb and fb/vref2 inputs will be fnom/2 or fnom/4 when the part is configured for frequency multiplication by using a divided qfb and qfb and setting ds[1:0] = mm. using the ds[1:0] inputs allows a different method for frequency multiplication (see divide selection table). |
