unusual facts about clock signal


Oscillator start-up timer

When a crystal oscillator starts up, its frequency is not constant, which causes the clock frequency to be non-constant.


Bit-synchronous operation

Bit-synchronous operation is a type of digital communication in which the data circuit-terminating equipment (DCE), data terminal equipment (DTE), and transmitting circuits are all operated in bit synchronism with a clock signal.

Display driver

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, voltage, current, timing and demultiplexing to make the display show the desired text or image.

IEEE 1394

The NRZ signal sent is fed with the clock signal through an XOR gate, creating a strobe signal.
