pulses.
Index pulse type
Gated
The index pulse is high (Logic 1 or 
True) only when the selected 
division ratio has been satisfied and 
the A and B phases are High.
Table 1.F I/O Filtering
High Frequency Filtering.
High Frequency filtering is provided on all 
power, digital and analog I/O lines as 
appropriate.
Over-Voltage Clamping
Over-voltage clamping is provided on the 
power supply inputs, the quadrature and 
index outputs, and the “EXT LINE SPEED 
IN” input.
