This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

At their core, CDR circuits combine elements such as phase detectors, digital loop filters and voltage-controlled oscillators, to reconstitute a reliable clock signal from sometimes noisy or ...

When the clock alarm is activated at a time set by the user, electromagnetic relay in the circuit is energised for a short duration, controlled by the timer IC 555. Contacts of the relay can be used ...

The screen on Circa is a 5.5-inch AMOLED panel, which seems like a bit of overkill for an alarm clock, but also means that there’s less light blasting at you in the middle of the night.

2. Clock Domain Crossing Types . 2.1 Synchronous Clock Domain Crossings . Clocks which have a known phase and frequency relationship between them are known as synchronous clocks [6]. The clocks ...

Clock circuit design explained. A common challenge facing many semiconductor companies is the push for higher data transmission speeds to drive ever higher system performance. When dealing with clock ...
