DS1687-3 is a highly efficient and reliable clock/timing technology that provides precise time keeping and real-time clock logging. It is a sophisticated timing device especially suitable for imaging, security and industrial applications as it offers excellent accuracy and a wide range of features.

The DS1687-3 is designed to receive an external signal from a GPS receiver which can then be utilized for time-stamping and precise time-stamping operations with sub-second resolution. This makes the DS1687-3 especially useful for time-stamping images and other media used in security or industrial applications.

The clock speed is managed by a 32 Khz quartz crystal oscillator for superior timekeeping accuracy. In order to accurately track time, the DS1687-3 uses a frequency synchronized clock (FSClk) and a programmable prescaler to regulate the exact frequency of the clock pulses. This frequency is then used to accurately determine the duration of the clock cycle, which is then used to accurately determine the count of the programmable counter.

The working principle of the DS1687-3 involves the use of a timer that records elapsed count. This enables the accurate tracking of time over long periods of time, while also providing an extremely accurate time-stamping feature. Additionally, the two programmable counter inputs can be used to provide a real-time clock (RTC) logging feature. These inputs can be used for functions such as time-stamping the images and other media used in the application. Moreover, the DS1687-3 also supports external voltage-controlled oscillator (VCO) inputs, allowing for frequency adjustment without the need for external oscillators.

The DS1687-3 is ideal for time-stamping applications, particularly in imaging, security, and industrial applications due to its precise time-stamping and accurate timekeeping features. With these features, the DS1687-3 provides an automated, accurate and highly reliable way to manage time. Output features include an internal 32 Khz quartz crystal oscillator, two programmable counter inputs and one external VCO input.

The DS1687-3 is a powerful and reliable clock/timing technology that allows precise time keeping and real-time clock (RTC) logging in a wide range of applications. The two programmable counters, frequency synchronized clock (FSClk), and external VCO input allow for precise time-stamping and precise time-stamping operations with sub-second resolution, making the DS1687-3 a must-have for imaging, security and industrial applications.
