Working Principle of the DS1693+

The DS1693+ is an oscillator (crystal) operating in the range of 4 Hz to 20 MHz. It supports both a crystal oscillator and RC oscillator modes. When the crystal is selected, an external XTAL1 and XTAL2 crystal is connected to the CLK and CLKb pins, respectively. The XTAL2 pin is then connected to the Vcc supply. The DS1693+ also supports a built-in 12 kHz oscillator that can be enabled through the configuration bits.

The oscillator output is divided down to the size required by the user application. The internal frequency synthesizer is used to generate a low jitter output clock with a frequency of up to 3.2 GHz, with the option of 2GHz and 400MHz. The output frequency can also be selected to optimize the power consumption and performance of the application.

The DS1693+ provides several safety and reliability features, such as an auto-trim register that is used to adjust the clock accuracy in real time, and a battery back-up circuit that can support an extended backup time. The device also features a wide range of power saving features, including a low-power mode and a deep sleep mode, which help to reduce power consumption when not in use.
