Abstract
A data processor has an input synchronizer (10) which is dynamically enabled by a plurality of control signals provided by a user of the data processor. When the plurality of control signals has a predetermined logic level, a bias generator enable circuit (18) enables a bias generator (16). Subsequently, bias generator (16) enables a differential amplifier (12) to synchronize an asynchronous input signal to an operating frequency of the data processor. When the plurality of control signals does not have the predetermined logic level, bias generator enable circuit (18) disables bias generator (16). Subsequently, differential amplifier (12) is disabled and the asynchronous input is not synchronized with the internal operating frequency of the data processor. Therefore, because the user may choose the logic levels of each of the plurality of control signals, the user may dynamically disable input synchronizer (10) to minimize the power consumption of the data processor.
