Mikroe Clock Gen 4 Click contains a clock generator and a multiplier/jitter reduced clock frequency synthesizer. The board features the Cirrus Logic CS2200-CP analog PLL architecture comprised of a Delta-Sigma fractional-N frequency synthesizer. The clocking device utilizes a programmable phase lock loop and allows frequency synthesis and clock generation from a stable reference clock. It generates a low-jitter PLL clock from an external crystal, supports both I2C and SPI for full software control. It also has a configurable auxiliary clock output. The board is ideal for MCU clock source, or in applications like digital effects processors, and digital mixing consoles.
