The Clock Gen 2 Click Board™ is an accurate square wave generator that can generate a clock signal in the range from 260kHz to 66.6MHz. It generates a square wave in the frequency of 66.6MHz, which is then processed by the prescaler, which can be set in the range from 20 up to 28. This allows the full frequency range to be achieved on the output. The DS1087L, a 3.3V spread-spectrum Econ Oscillator, used on the Clock Gen 2 Click Board™, offers the spread-spectrum function, which can be controlled via the IC pin and register setting. This allows reduced EMI, especially on the high frequencies. Finally, the DS1087L offers a NV memory (EEPROM), which is used for storing the values of the configuration registers.
