AK8140A
Programmable Clock Generator
Description
AK8140A is AKM’s High-performance programmable clock generator.
AK8140A generates up to four output clocks from a single input frequency with two fractional-N PLLs.
Each output can be programmed for any frequency up to 230MHz.
AK8140A is available in a 24-pin ETSSOP package.
