A system includes a transceiver having mixers, variable gain amplifiers, a modulator, a local oscillator and power amplifiers that may receive control signals generated by a Digital-to-Analog Converter (DAC). The DAC may include a multiplexer that receives digital values that are transferred to a DAC core, converted to analog values, and stored in sample-and-hold circuits. The one DAC may service multiple devices within the transceiver with control signals. A smart timer may generate select signals to the multiplexer and sample-and hold circuits to prioritize updating of the control signals.
