AK8119A

ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8119A
Features
Description
The AK8119A is a single clock generator IC with
an integrated PLL. It can generate either a
40.5MHz or 36.0MHz clock from a 12MHz master
clock input frequency. Through pin control, the
output can be enabled or disabled, and the
frequency can be changed. The high performance
PLL locks to the master clock input, generating a
low jitter, highly accurate clock output without an
external crystal.
Output Frequency Range:
40.5MHz / 36.0MHz (Selectable)
Input Frequency:
12MHz
Low Jitter Performance:
15 ps (Typ.) Period, 1σ
Low Current Consumption:
3.0mA (Typ.)
Output Load:
15pF (max.)
Supply Voltage:
2.7 – 3.6V
Operating Temperature Range:
-20 to +85℃
Package:
6-pin USON (lead-free)
Applications
Digital Still Camera
Body Size 2.0mm x 1.8mm

Output clock frequency is selectable to 40.5MHz or 36.0MHz by setting the
FSEL pin. In power down mode (OE = “L”), this pin is “L”.
CLKOUT output enable control
“L”: CLKOUT=”L” and power down.
Clock frequency select
“L”: 40.5MHz, “H”: 36.0MHz

“H”: active

Clock input (12MHz)
Place the AK8119A 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.
