If you did much dismantling of PCs back in the 1980s and 1990s, you might be familiar with the Dallas Semiconductor range of potted real-time clock modules. These were chunky dual-in-line devices ...

Occasionally you might need a simple clock module for various projects. A small CMOS clock module, such as the one presented here, is not capable of offering as much precision as a clock module built ...

As technology advance, we see complex SoCs emerging in the market with multiple interfaces. These complex SoCs can have multiple clocks driving multiple modules, which may be getting divided further ...
