I need an integrated high performance stepper motor driver (5000  
steps/sec) that has PULSE and DIRECTION as its control inputs (which will  
be supplied from a controller circuit), and can drive at least 1amp in  
each phase of the motor. 

If you know about any circuits matching these specs please let me know.

The reason that I need this is that the system I have, seems to have an  
upper limit of about 600 steps/sec, and that is not sufficient for our  
purpose.

Please answer by email.
