ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8113
Features
Description
The AK8113 is a single clock generator IC with an
integrated PLL. It can generate either a
74.17582MHz or a 74.25MHz 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.
Output Frequency Range:
74.17582MHz / 74.25MHz (Selectable)
Input Frequency:
27MHz
Low Jitter Performance:
15 ps (Typ.) Period, 1σ
Low Current Consumption:
3.8mA (Typ.)
Output Load:
15pF (max.)
Supply Voltage:
2.7 – 3.6V
Operating Temperature Range:
-20 to +85℃
Package:
6-pin SON (lead-free)

Output clock frequency is selectable to 74.17582MHz or 74.25MHz by
setting the FSEL pin. In power down mode (OE = “L”), this pin is “L”.

Clock input (27MHz)
Place the AK8113 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.
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.
