Abstract:
A transmitter system includes a digital phase rotator, a phase rotation controller, and a digital radio-frequency (RF) transmitter. The digital phase rotator receives a first constellation data, and applies a digital phase rotation to the received first constellation data to generate a second constellation data. The phase rotation controller configures the digital phase rotation. The digital RF transmitter receives a digital input data derived from the second constellation data, and converts the digital input data into an analog RF output.
Abstract:
A reconfigurable circuit block includes a rate-conversion circuit, a processing circuit, a first asynchronous interface circuit, and a second asynchronous interface circuit. The rate-conversion circuit converts a first input signal into a first output signal. The processing circuit processes a second input signal to generate a second output signal. The first asynchronous interface circuit outputs a third output signal asynchronous with the first output signal. The second asynchronous interface circuit outputs a fourth output signal asynchronous with the second output signal. The controllable interconnection circuit transmits the third output signal to the processing circuit to serve as the second input signal when controlled to have a first interconnection configuration, and transmits the fourth output signal to the rate-conversion circuit to serve as the first input signal when controlled to have a second interconnection configuration.
