Title:
OSCILLATOR AND DEVICE
Document Type and Number:
Japanese Patent JP2023020014
Kind Code:
A
Abstract:
To provide an oscillator and a device that can achieve both output of a clock signal and data communication.SOLUTION: An oscillator 4 includes: a vibrator 10; an oscillation circuit 30 that generates an oscillation signal OSC by using the vibrator 10; a clock output terminal TCK; an output circuit 90 that outputs a clock signal CK to an external processing apparatus 100 through the clock output terminal TCK; a first terminal TDA; and an interface circuit 80 that performs communication with the processing apparatus 100 using a data signal DA. In the communication, the output circuit 90 outputs the clock signal CK to the processing apparatus 100 being a master in the communication, and the interface circuit 80 being a slave in the communication receives the data signal DA transmitted from the processing apparatus 100 and synchronized with the clock signal CK through the first terminal TDA, or in synchronization with the clock signal CK, transmits the data signal DA to the processing apparatus 100 through the first terminal TDA.SELECTED DRAWING: Figure 1
