Clock Gen 5 Click is a compact add-on board that contains a digital programmable oscillator solution. This board features the LTC6903, a low-power self-contained digital frequency source providing a precision frequency from 1kHz to 68MHz set through a 3-wire SPI digital interface from Analog Devices. The LTC6903 features a proprietary feedback loop that linearizes the relationship between digital control setting and frequency and provides a smaller, more reliable, and vastly more versatile clocking solution. The frequency between 1kHz and 68MHz is set by a 16-bit control word, typically accurate within 1.1% with a resolution of 0.1% or better. This Click board™ is suitable for applications such as MCU clock source, clock source for a switched capacitor filter, or general replacement for a DAC/VCO combination.
