Mikroe Clock Generator Click is an ideal replacement for crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), and fanout buffers. The click features the Silicon Labs Si5351A I2C configurable clock generator based on a PLL + high-resolution MultiSynth fractional divider architecture. It can generate any frequency up to 200MHz on each of its outputs with 0ppm error. The Si5351A is capable of generating synchronous or free-running non-integer related clock frequencies at each of its outputs (CLK0, CLK1, and CLK2). This allows one device to synthesize clocks for multiple clock domains in a design.
