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.
