(5) Reference Pulse Input Timing
Reference pulse form and input timing are as shown below.
Reference Pulse Form
Sign + pulse train input
(SIGN + PULS signal)
Maximum reference fre-
quency: 4 Mpps*
(In case of open-collector
output, maximum refer-
ence frequency: 200 kpps)
Forward direction pulse +
reverse direction pulse
Maximum reference fre-
quency: 4 Mpps*
(In case of open-collector
output, maximum refer-
ence frequency: 200 kpps)
Two-phase pulse train with
90° phase differential
(phase A + phase B)
Maximum reference fre-
quency: 1 Mpps*
