Abstract: Techniques for the design and use of a digital signal processor, including for processing transmissions in a communications 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. For a limited period of time, a low phase output level is forced. 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: In an embodiment, a method is disclosed that includes receiving a clock signal at a delay chain of a circuit device and determining a value of the clock signal at a selected point within the delay chain. The method also includes adjusting the selected point when the value does not indicate detection of an edge of the clock signal.

Abstract: Techniques for the design and use of a digital signal processor, includin g (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 lo w phase output level in the clock output in response to a low phase input le vel in the first clock output. For a limited period of time, a low phase out put 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 provi ding the clock output in response to the second clock input occurs during th e low phase input level in the second clock input signal. Then, the output o f the clock multiplexer follows the phase level of the second clock signal.

Abstract: Un procedimiento para detectar una parte deseada de una señal de reloj (102) para determinar una fluctuación de reloj, que comprende: recibir (602) la señal de reloj (102) en una cadena de retardos (206) de un dispositivo de circuito; seleccionar un punto de muestreo dentro de la cadena de retardos (206); muestrear (604) la señal de reloj (102) en el punto de muestreo seleccionado; determinar (606) un valor de la señal de reloj (102) en el punto de muestreo seleccionado en la cadena de retardos (206), en el que el valor de la señal de reloj representa un nivel de la señal de reloj en el punto de muestreo seleccionado; y comparar (608) el valor de la señal de reloj (102) en el punto de muestreo seleccionado para determinar si el valor de la señal de reloj indica la parte deseada; si el valor no indica la parte deseada de la señal de reloj (102), ajustar el punto de muestreo seleccionado hasta que el valor indique la parte deseada.
