Description
The AK8133 is a member of AKEMD’s low power multi clock generator family designed for a high quality audio cock with high performance C/N. The AK8133 generates different frequency clocks from a 27MHz crystal oscillator or external 27MHz clock input. It provides them to up to four outputs configured by pin-setting. Both circuitries of XO and PLL in AK8133 are derived from AKEMD’s long-term-experienced clock device technology, and enable clock output to perform low jitter and to operate with very low current consumption. The AK8133 is available in a 16-pin SSOP package.
