In CPU, SOC, GPU, and PC-on-chip, I/O power consumption can be significant. To improve power efficiency, I/O bundles in group of 4, 8, or 16b, should scale their data rate according to the application requirements. However, clocking architecture impo

A VCO used in a PLL inside a wireless transceiver can be sensitive to interference from other radio circuitry (e.g. on-chip PA), components of the SoC system (e.g. clocks and their harmonics) and nearby radios. To prevent VCO pulling by the PA, fract
