Description

The AK8133 is a member of AKEMD’s low power multi clock generator family designed for a high quality audio clock with high performance C/N. It generates different frequency clocks from a 27MHz crystal oscillator or external 27MHz clock input. The AK8133 provides 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, enabling the clock output to perform low jitter and operate with very low current consumption. The AK8133 is available in a 16-pin SSOP package.
