| 21. | The two zones were kept synchronous by a clock signal carried by the crosslink cables.
|
| 22. | The clock signal is always controlled by the programmer.
|
| 23. | The usual use of a clock signal is to synchronize transitions in sequential logic circuits.
|
| 24. | For example, a clock signal is subject to the delays of any other electrical signal.
|
| 25. | Dual-link DVI displays use two of the TMDS / DisplayPort transmitters and one clock signal each.
|
| 26. | The process of extracting the clock signal from the data stream is where jitter is introduced.
|
| 27. | Single-link DVI displays and HDMI displays use one TMDS / DisplayPort transmitter and one clock signal each.
|
| 28. | "Analog clock " signals are equivalent to the clock signal at pin 3 of DIN sync interface.
|
| 29. | Like modems, the system locked onto the signal rise and fall times to recreate a clock signal.
|
| 30. | It can resume processing when the clock signal is restarted, as long as it is kept powered.
