Embodiment 1

[0017] like figure 1 Show, a high -precision clock phase control circuit, including a multi -phase clock generated circuit module and a programmable phase selection circuit module.And at least one protective unit, the programmable phase selection circuit module includes multiple multi -road selection units and phase combination circuits, which are connected separately from a single multi -road selection circuit and a single phase selection circuit.

[0018] Among them, the selection unit contains an hour input and a signal input pink, which contains an hour input and one signal input pin.

[0019] Among them, the clock generated circuit module includes the first phase selection circuit, the second phase selection circuit and other phase phase selection circuits.

[0020] Among them, the multi -road selection unit includes the first multi -road selection unit, the second multi -road selection unit and other multi -way options.

[0021] Among them, the phase combination circuit incl...

Embodiment 2

[0027] The rest is the same as the embodiment 1. The difference is that the selection unit contains an hour input and one signal input.The clock input of the selection unit inputs the pin to receive a phase of the clock signal, using the signal of the selected unit to input the pin to receive a selection signal, and generates a one output signal based on the phase clock signal and the selection signal.The clock inputs the pin to receive the phase clock signal, and uses the one -signal input of the protective unit to input the pound of the switch signal to receive the encoding data, and use the other signal of the protective unit to enter the pound of the poundData, according to the clock signal of the phase and the coding data of the switching signal, generate a selection signal.

Embodiment 3

[0029] The rest is the same as the Example 1, the difference is that the selection unit contains two clock input pins and one signal input pins.The one -hour input of the selected unit inputs the pin to receive the current phase clock signal, and use the other clock of the selected unit to enter the pink to receive the previous phase of the clock signal, and use the signal of the selected unit to enter the pin to receive a selection signal to receive a selection signal.According to the multiple phase clock signals and the selection signal, a one -output signal is generated, and the clock input of the protective unit inputs to receive the current phase clock signal.The encoding data of the switching signal is used to input another coding data of the switch signal using the other signal of the protective unit, and generate the selection signal based on the current phase clock signal and the encoding data of the switching signal.

Description

Technical field [0001] The present invention involves the field of electronic circuits and specifically involves a high -precision clock phase control circuit. Background technique [0002] The clock frequency refers to the basic frequency of the clock in the synchronous circuit. It is measured with "several second cycles" and the measured unit uses the SI unit Hz (Hz).Numerous transistors in digital circuit and analog circuit chips work in the switch state. Their in -depth and control movements are performed according to the rhythm of the clock signal.If the clock frequency is too high, the state of the transistor may be too late to change, and a deadlock or random operation.At the same time, due to the needs of the circuit working status, the phase of the clock needs to be adjusted. The existing clock phase adjustment usually depends on the implementation of separate chips, which increases the cost and occupies the area of the PCB board.The invention introduces a high -precisio...
