Figure 8. Ref Sine Input Square Wave Reference Input the square wave ref input stage is shown in figure 9. the stage is designed to accept square wave inputs from cML to cMos levels. slightly degraded phase noise performance may be obtained with quasi sine 1 Vpp inputs. it may be necessary to attenuate very large cMos levels if absolute best in close phase noise performance is required. input reference should have a noise floor better than -160 dBc/hz to avoid degradation of the input reference path.
