About MC3PHAC (3 phase motor controller)

I would like to build an inverter to drive a motor, and my first idea was about to use the monolithic intelligent motor controller with an standard IGBT module. But reading the MC3PHAC data sheet, i found out that its synchronous motor frequency is from 1Hz to 128Hz, which is too low for me. If I change the crystal/resonator frequency, will it be necessary to change all the small components values (I mean, capacitors and resistors) that are shown in the data sheet? Do you know about any other motor controller that could achieve a larger synchronous motor frequency?
I hava attached the data sheet.
I really hope someone could help me.
Thanks in advance.
