1.8V/3.0V Single-PLL
Clock Generator
AK8150B
Description
The AK8150B is a single-PLL clock generator IC with
two outputs. The high performance PLL locks to the
master clock input, generating a low jitter, highly
accurate clock output without an external crystal.
The integrated PLL generates 12MHz with 36 MHz
input clock. The device has another output, REF
which is to be ICLK or ICLK divided by two.
The AK8150B has two kinds of voltage supply pins.
One is for the core and the other is for each of the
two output buffers. The core requires 1.8V supply
and the output buffers require 1.7V - 1.9V or 2.7V -
3.3V supply. Not only the output but also the input
accepts 1.8V or 3.0V input clock from Crystal
Oscillator.

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.
