Silicon Labs clocks generate any combination of frequencies/ formats with low jitter. Clock buffers provide integrated format/voltage level translation. By consolidating more timing functions into fewer devices, Silicon Labs delivers complete clock tree solutions that minimize system cost and complexity.
