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.
