摘要： An XOR phase detector for a phase-locked loop PLL comprises an XOR gate which has an input for a periodic reference signal and another input connected to a frequency divider of the PLL. A level shifter has a level shifter input connected to an output of the XOR gate and a level shifter output connectable to a voltage-controlled oscillator VCO of the PLL. The level shifter is connectable between low and high voltage providers and has a high level and a low level. The level shifter is arranged to deliver at its output the high level or the low level depending on whether the voltage at the output of the XOR phase detector is low or high. The level shifter further has a setpoint input for setting the high level to a setpoint level.

摘要： A device for regulating the amplitude of a chrominance signal includes a variable gain amplifier having an input receiving a sub-carrier signal, and an output providing a regulated sub-carrier signal. The gain of the amplifier is controlled by two regulation loops. The first regulation loop operates during the duration of the reference burst. The second regulation loop operates during the visible line. Each of these loops include an up/down counter controlled by a clock. A digital-analog converter has an input receiving the output signals from the first and second up/down counters. An output signal from the digital-analog converter is connected to the gain control of the amplifier. The digital-analog amplifier is controlled by another clock.
