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.
