The AK8147DV2 is a member of AKM’s High-performance programmable clock generator.
The AK8147DV2 generates up to six output clocks from a single input frequency with four fractional-N PLLs.
Each output can be programmed for any frequency up to 148.5MHz.
PLLs in AK8147DV2 are derivedfrom AKM’s long-term-experienced clock device technology, and enable clock output to perform low jitter and to operate with very low current consumption. In addition, enables ‘Dynamic Frequency Control’. The AK8147DV2 is available in a 32-pin QFN package.
