The AK8137A is a member of AKM’s low power multi clock generator family designed for a feature rich DTV or STB, requiring a range of system clocks with high performance. The AK8137A generates different frequency clocks from a 25 MHz crystal oscillator and provides them to up to four outputs configured by pin-setting. PLL in AK8137A are derived from AKM’s long-term-experienced clock device technology, and enable clock output to perform low jitter and to operate with very low current consumption. The AK8137A is available in a 20-pin SSOP package.
