Description
The AK8150C 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 38 MHz
input clock. The device has another output, REF
which is to be ICLK or ICLK divided by two.
The AK8150C 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.
