PG-D2/PG-X2/PG-W2
The maximum response frequency is 300kHz.
Use the following equation to computer the output frequency of the PG (f
PG
).
A separate power supply is required if the PG power supply capacity is greater than 200mA. (If momentary power loss must be
handled, use a backup capacitor or other method). See Fig 2.25.
