Description: 3 Phase / Pulse Width Modulation Waveform Generator

Features

* s Fully Digital Operation RD
* (DS†) NC ALE
* (AS†) RST CLK CS TRIP MA818 34 33 32 31 30 s Interfaces with Most Microprocessors s Wide Power-Frequency Range s Carrier Frequency Selectable up to 24kHz s Waveform Stored in External PROM/EPROM s Double Edged Regular Sampling s Selectable Mini

Applications

* Power frequency ranges of up to 4kHz (with 12.5MHz clock) are possible, with the actual output frequency resolved to 12-bit accuracy within the chosen range in order to give precise motor speed control and smooth frequency changing. The output phase sequence of the PWM outputs can also be changed t
