Description
The AK8130F 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 AK8130F generates different frequency clocks from a 27MHz crystal oscillator and provides them to up to four outputs configured by pin-setting. The on-chip VCXO accepts a voltage control input to allow the output clocks to vary by ±110 ppm for synchronizing to the external clock system. Both circuitries of VCXO and PLL in AK8130F 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 AK8130F is available in a 16-pin SSOP package.
