AKD8181B  
Power  
There are the following three power supplies.  
※If you have configured a termination circuit with resistor only (Pattern A or B), it becomes possible to  
evaluate even without applying power to the VDD-2V terminal.  
The core power supply of AK8181B (3.3V)  
- VDD  
The core power supply of AK8181B (GND)  
- VEE  
Power supply for the end of the output load resistor (=VDD-2V)  
- VDD-2V  
Note) GND of the SMA terminal is connected to the VEE inside the substrate.  
Clock input  
AK8181B inputs the clock selected by CLK_SEL switch. (External input or crystal)  
The clock input signal can terminate at 50Ω if needed. (50Ω is connected to R2 pattern)  
Inputs 266MHz or less.  
Output load circuit  
It can terminate by the following three methods. (Pattern A/B/C)  
The state of initial shipment is Pattern A.
