Mikroe Clock Gen 3 Click features a low-power self-contained digital frequency source that provides a precision frequency from 1kHz to 68MHz. The board is an I2C configurable clock generator that features the Analog Devices LTC6904. It requires no external components other than a power supply bypass capacitor. It operates over a single wide supply voltage range of 2.7V to 5.5V. The LTC6904 features a proprietary feedback loop that linearizes the relationship between digital control settings and frequency. It's ideal for applications like a microcontroller clock source, clock source for a switched capacitor filter, or general replacement for a DAC/VCO combination.
