NOTE
„
When the switch is ON, it means logic 0.
„
A-/A and B-/B are the input signals of PG card. A/O-/A/O and B/O-/B/O are the line driver
outputs of the frequency divider measured by the differential probe.
„
Bit 0-4 are the denominators for the frequency divider. Bit 0 is the low bit (EX: the setting
of 10110 is that the input signal divides by 13).
„
When the output pulse type of frequency divider is set to 0, A/O-/A/O, B/O-/B/O, OA-GND
and OB-GND are the outputs of frequency divider.
„
When the output pulse type of frequency divider is set to 1, B/O-/B/O and OB-GND are
the indication of phase A and B. (EX: LOW means A leads B and HIGH means B leads A).
A/O-/A/O and OA-GND are the output of frequency dividers.
„
When changing the denominator of the frequency divider or output type, it needs to clear
the counter value by clock reset bit before operation.
