The high speed input works directly with 5 V input, 3.0 to 6.0
V range, without the use of a current limiting resistor. To
operate the input with voltages higher than 5 V, an external
current limiting resistor is required in series with the input.
The input current should be in the range of 9 to 24 mA for
proper operation. The following table lists the recommended
current limiting resistors for supply voltages greater than 5 V.

In Step-Dir Position Mode the transition edge from LED
current to no LED current yields a step count. The transition
edge from no LED current to LED current yields no action.
NOTE
Maximum step frequency is 1.5 MHz
Minimum pulse width is 250 ns
NOTE
For single ended operation, it is recommended that both wires (J4-10 and
J4-11) run in the cable be terminated at the control source (differential
noise).
High Speed Input
Differential Drive
A differential drive is recommended for the Step Input. To
provide maximum noise immunity, drive the high speed
input differentially from 5 V logic through twisted pair wiring.
The differential driver needs to deliver a minimum of 3.0 V
to the input terminals on J4. A CMOS driver is
recommended.
