Description
The AK8111 is a single clock generator IC with an
integrated PLL. It can generate either a
12.288MHz or a 24.576MHz clock from a 27MHz
master clock input frequency. Through pin control,
the output can be enabled or disabled, the
frequency can be changed, and the device can be
placed in a power-down mode. A high performance
PLL locks to the master clock input, generating a
low jitter, highly accurate clock output without an
external crystal.

3 CLKOUT OUT
Clock output
Output clock frequency is selectable to 12.288MHz or 24.576MHz by setting
the FSEL pin. In power down mode (OE = “L”), this pin is “L”.

6 CLKIN IN
Clock input (27MHz)
Place the AK8111 in power down (OE = “L”) mode when an input clock is not
supplied. Unstable input to the CLKIN causes the unstable CLKOUT signal.
DC input to the CLKIN also causes the unstable CLKOUT signal.

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.
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.
