The AK8146C is a low power multi clock generator which generates different frequency clocks from a external clock input. It provides two outputs of 12MHz and 13.5MHz. PLL in AK8146C 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 AK8146C is available in a 8-pin USON package.

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. AKEMD recommends that this device is handled with appropriate precautions.

Note:
1 Power to VDD requires to be supplied from a single source. A decoupling capacitor of 0.1mF for power supply line should be installed close to each VDD pin.
