Low power digital adaptive termination network |
摘要 |
An apparatus, method, microprocessor device and computer program for configuring a termination network of a communication device includes a voltage comparator for comparing a voltage across the termination network with a reference voltage; a logic arrangement for setting a digital control vector in response to a state returned by said voltage comparator; and a first switching apparatus for activating a first weighted-value resistor in response to the setting of the digital control vector. At least a second switching apparatus for activating a second weighted-value resistor, and wherein each of the first and the second weighted-value resistors is represented by a value in the digital control vector may be provided, the first and second resistors are connected in series or in parallel. The digital control vector may be stored in a logic register and distributed to a plurality of termination networks. The logic arrangement may include a finite state machine.
