Abstract
Provided is an interface circuit having a terminator, in which the terminator includes parallel-connected first to an Nth resistance elements, where N is an integral number equal to or more than 2, and a first to an nth cut-off elements connected in serial with each of the corresponding n(1≦n<N) first to the Nth resistance elements of the first to the Nth resistance elements.
Claims17
An interface circuit comprising:
- a terminator,
- the terminator including parallel-connected first to an Nth resistance elements, where N being an integral number equal to or more than 2,
- a first to an nth cut-off elements being connected in serial with each of the corresponding n(1≦n<N) first to the Nth resistance elements of the first to the Nth resistance elements, and
- each of the Nth resistance elements being connected in serial with at least two other resistance elements.
