Part Number: PGA411Q1EVM
A resolver design calls for a 7 Vpp resolver with a transformer ration n =0.5 placed 50 feet from the PGA411-Q1 Resolver decoder IC. I get a peak voltage of 0.58V at the pins of the external amplifier circuit using simulation software. The application is motor control for electric propulsion. Note that my circuit model did not include noise on the twisted pair connections that can cause additional issues.
I am wondering if do you have a model or application documentation developed to validate if 50FT transmission length is a physically feasible design and what are typical transmission lengths between the resolver and IC circuit? In addition, what is the maximum allowed phase shift error allowed in the excitation sine wave and the induced resolver outputs?
