(1) Typical values are stated for V
CC
= +3.3V and T
A
= +25°C.
(2) Cable driver additive jitter is measured with the input AC coupled.
(3) Specification is ensured by characterization.
(4) Return loss is dependent on board design. The LMH0387 exceeds this specification on the SD387 evaluation board.
