An Overview of LCSC Clock and Timing
Clock/Timing are two concepts but related to each other. The clock is a periodical signal with high and low states oscillating in a constant frequency. Timing in the digital system shows the relationship between two or more signals and how each signal changes concerning the others. In the electronic industry, Clock/Timing is more related to the component, a small integrated device, that performs specific tasks for different applications concerning timing purposes.
What are the Applications of Clock and Timing?
The applications of clock/timing ICs vary depending on their initial purpose when invented. The datasheet electrical engineering uses the most to identify whether the clock/timing ICs are suitable. For example, NE555DR ( under LCSC category: Timers/Counters | Clock/Timing), according to the datasheet, can apply to three areas, including Fingerprint Biometrics, Iris Biometrics, and RFID Reader.
What are the Working Principles of Clock and Timing IC?
Under the Real Time Clock | Clock/Timing LCSC category, the DS1302Z datasheet's working principle is below.
As shown in the figure, after the RST signal is valid, the shift register unit will receive the 8-bit instruction byte serially from the I/O under the control of the SCLK synchronous pulse signal, and then convert the 8-bit instruction byte from serial to parallel and send it to the ROM instruction decoding unit. The ROM instruction decoding unit decodes the 8-bit instruction byte to determine the address and read/write status of the internal register. Then, under the control of the next SCLK synchronous pulse signal, the 8-bit data is written into or read out of the corresponding register. Data transmission can also be carried out in a multi-byte mode, first writing the 8-bit corresponding instruction byte, and then continuously writing or reading the data bytes into or out of the calendar/clock register (or RAM unit) under the synchronization of the continuous SCLK pulse signal. The number of SCLK pulses is 8 plus 8 in the single-byte mode and 8 plus a maximum of 248 in the multi-byte mode.
