Abstract
A radio-frequency amplifier can have a radio-frequency input configured to receive a radio-frequency signal and a control input for receiving a control signal. The radio-frequency signal can be generated using a first group of digital-to-analog converters (DACs), whereas the control signal can be generated using a second set of DACs. Data intended for the first group of DACs can be fed through a first set of retiming circuits and a first crossbar circuit. Data intended for the second group of DACs can be fed through a second set of retiming circuits and a second crossbar circuit. A low skew clocking interface and constant latency control and clock domain cross circuits can be employed to ensure that data streams arriving at the first group of DACs are time aligned with data streams arriving at the second group of DACs.
