Termination resistor circuit for achieving highly versatile interface circuit and signal transmission system having the termination resistor circuit

摘要

A termination resistor circuit, which is provided in an interface circuit through which signals are transferred, has a first termination resistor block and a second termination resistor block. The second termination resistor block differs in configuration from the first termination resistor block. The termination resistor circuit is switched between the first termination resistor block and the second termination resistor block. Therefore, the termination resistor circuit can provide a highly versatile interface circuit.
