摘要： Disclosed is a system for selectively enabling intermediate data processing of digital signals external to an integrated circuit (IC). The system comprises a transcoder, a codec connected to the transcoder, and a data processor located externally to the IC. In response to a strobe signal, a programmable switch diverts digital signals between the transcoder and the codec to a data path from the IC to the external processor. The digital signals are formatted within the IC for processing by the external processor. The externally processed digital signals are returned to the IC via a data path from the external processor. The digital signals are then reformatted within the IC for further processing by the IC.

摘要： A dual-mode baseband controller enables a single integrated circuit to support either In-Phase Quadrature (I-Q) or Non-Return to Zero (NRZ) radio-frequency transmitter architectures for use in second generation (CT2) cordless telephones. A radio frequency (RF) interface circuit controls output signals to support either the I-Q architecture or the NRZ architecture, depending on a MODE control bit received from a controlling integrated circuit. The RF interface circuit comprises an I-Q waveform generator, four multiplexers, two digital-to-analog converters, a buffer, interconnecting circuitry, and a timing controller operating under configurable software control.

摘要： A communication circuit designed to be coupled to a radio receiver so as to receive a data signal and a receive signal strength indicator signal indicative of radio carrier strength therefrom, and further designed to be coupled to a controller, the communications circuit including a first, second, third, and fourth subcircuit. The first subcircuit receives the receive signal strength indicator from the receiver, determines radio carrier strength therefrom, and transfers the determined strength information to the controller. The second subcircuit receives the data signal from the receiver, determines if there are bit error within that signal, and transfers its determinations to the controller. The third subcircuit receives the data signal from the receiver, determines if there is jitter therein, and transfers its determinations to the controller. The fourth subcircuit is coupled to the second and third subcircuits to receive the output thereof, and is further coupled to the controller so as to receive output therefrom, the fourth subcircuit acting in response to the outputs to suppress signal noise.

摘要： A clock generator and interrupt bypass circuit for use in reducing the power consumption of the electrical system in which they are implemented. The clock generator provides module clock signals for sequencing modules within the same electrical system, and is capable of generating those module clock signals when in an active mode, and of not generating those module clock signals when in a stand-by mode. The clock generator is further capable of providing a delay of a predetermined length from a request to enter shut-down mode to actual entry into shut-down mode, allowing time to prepare the electrical system for shut-down mode. The interrupt bypass circuit provides a means of leaving shut-down mode in the event that the relevant interrupt requests have been masked.
