A circuit module comprises a first circuit chip ( 102 a) and a second circuit chip ( 102 b). Each circuit chip comprises a signal input ( 104 a, 104 b) and a reference input ( 106 a, 106 b). A first termination resistance ( 112 ) connects the signal inputs ( 104 a, 104 b) and a second resistance ( 114 ) connects the reference inputs ( 106 a, 106 b). A first termination resistance ( 116 ) connects the second signal input ( 104 b) to the termination voltage ( 120 ) and a second termination resistance ( 118 ) connects the second reference input ( 106 b) to the termination voltage ( 120 ). A first ratio between the first resistance ( 112 ) and the first termination resistance ( 116 ) corresponds to a second ratio between the second resistance ( 114 ) and the second termination resistance ( 118 ).
