The AK8153A is a high performance clock generator
IC with two outputs. It generates 12MHz clock by
dividing 60M or 72MHz input clock. And also outputs
REF clock which is to be ICLK.
AK8153A provides very low jitter and highly accurate
clock output without an external crystal.

Note:
(1) Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated
under “Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rating conditions for
extended periods may affect device reliability. Electrical parameters are guaranteed only over the recommended
operating temperature range.
ESD Sensitive Device
This device is manufactured on a CMOS process, therefore, generically susceptible to
damage by excessive static voltage. Failure to observe proper handling and installation
procedures can cause damage. AKM recommends that this device is handled with appropriate
precautions.
