There are 5 V and 12 V PG power supplies.
Check the PG power supply specifications before connecting.
The maximum response frequency is 300 kHz.
Use the following equation to computer the output frequency of the PG (f
A separate power supply is required if the PG power supply capacity is greater than 200 mA. (If momentary
power loss must be handled, use a backup capacitor or other method.)
