A phase output
Output the frequency divided encoder signal, comply with
the standard of TIA/EIA-422-B.
The output phase A pulse and phase B pulse is still
quadrature. When it rotates forward, phase B leads phase A
by 90º. When it rotates in reverse, phase A leads phase B
by 90º.
Frequency division and frequency multiplication with any
integer and decimal fraction is allowable.
The output signals have no isolation.
