    Abstract: Techniques for the design and use of a digital signal processor, including (but not limited to) for processing transmissions in a communications (e.g., CDMA) system. Reduced glitch occurs in switching from a first clock input to a second clock input driving a clock multiplexer. The clock multiplexer receives a first clock input and provides a clock output and determines a low phase output level in the clock output in response to a low phase input level in the first clock output. For a limited period of time, a low phase output level is forced irrespective of the phase level of the first clock input signal. The clock multiplexer receives a second clock input and determines a low phase input level in the second clock input signal. Switching to providing the clock output in response to the second clock input occurs during the low phase input level in the second clock input signal. Then, the output of the clock multiplexer follows the phase level of the second clock signal.

    Abstract: A circuit (100) including a logic gate (133) responsive to a clock signal (103) and to a control signal (104). The circuit also includes a master stage (101) of a flip-flop. The circuit further includes a slave stage (102) of the flip-flop responsive to the master stage. The circuit further includes an inverter (109) responsive to the logic gate and configured to output a delayed version of the clock signal. An output of the logic gate and the delayed version of the clock signal are provided to the master stage (101) and to the slave stage (102) of the flip-flop. The master stage is responsive to the control signal to control (122out) the slave stage.
