Attention: T o achieve o ptimal freq uency st ability, and in som e cases to meet the sp ecificatio n stated o n this d ata sheet, it is r equired
that the circu it co nnected to this TCX O o utpu t must have the equ ivalent input cap acitan ce that is sp ecified b y the nominal load
capacitance. Deviation s fr om the nom ina l load capacitance will have a g radu ated effect on the stability of ap pr oximat ely 20 p pb per p F
