Power
There are the following three power supplies.
- VDD
The core power supply of AK8180E (+1.25V or +1.65V)
- VSS
The core power supply of AK8180E (-1.25V or -1.65V)
- VTT
Power supply for the end of the output load resistor (GND)
Note) GND of the SMA terminal is connected to the VTT.
Clock Input
The clock input signal can terminate at 50Ω if needed. (50Ω is connected to R1 pattern)
Inputs 200MHz or less.
Output load circuit
Each output line is terminated to VTT with 50Ω.
