Abstract: A filter uses a digital integrator that establishes the sum, weighted by a coefficient B, of q1-bit input data arriving at a frequency F. The integrator includes a first p-bit shift-right register; a second q-bit shift-right register, circularly connected and storing the current input data in its most significant bits; and a full bit adder having two inputs respectively connected to the outputs of the first and second shift registers, and an output connected to the input of the first shift register. A sequencer enables the shifting of the first register during p clock cycles, and the shifting of the second register during q clock cycles starting b cycles after the beginning of the p cycles, number b being selected as a function of coefficient B.

Abstract: A digital phase comparator supplies digital values corresponding to the phase shifts between a first signal having a duty cycle of approximately 0.5 and a second signal. The comparator includes a one-way counter initialized at the frequency of the first signal and clocked by a clock signal having a high frequency with respect to the frequency of the first and second signals. A logic gate enables the counter when the first and second signals are in respective predetermined states. A phase shift is considered to be zero when it corresponds approximately to one half of the counter's capacity.

Abstract: A frequency synthesizer provides a synthesized signal. The synthesizer includes an oscillator that supplies a fast clock signal to a divider programmable by a digital data. The most significant bits of the digital data are provided to the programmable divider, and the least significant bits are provided to an accumulator that cooperates with the programmable divider to increment by one unit its division rank when the accumulator overflows. The synthesizer further includes a generator for generating n increasing delay phases of the synthesized signal; a comparator for comparing the content of the accumulator with n ranges of possible increasing values; and circuits for selecting, as the synthesized signal, the phase whose rank corresponds to the rank of the range within which the content of the accumulator is comprised.

Abstract: A device synchronizes an internal signal with respect to a reference signal, each signal comprising pulses normally occurring at a rated frequency. The device uses a phase comparator to analyze the phase of the internal signal and the reference signal and produce one logic state if the phase of the internal signal is in advance of the phase of the reference signal and a second logic state otherwise. A programmable frequency divider divides an internal clock signal by a first number if the phase comparator signal produces the first logic state or by a second number if the phase comparator produces the second logic state. A multiplexer provides the programmable divider with either the first number or the second number depending on the logic state produced the phase comparator. The device also includes a storage element for sequentially storing a predetermined number of the latest logic states of the phase comparator. The device also includes circuitry for decrementing the first number when the latest stored logic states of the phase comparator have a single occurrence of the first logic state and for incrementing the second number when the latest stored logic states of the phase comparator have a single occurrence of the second state.
