AM263P2-Q1: Query on using resolver cicuit for AM263p

Hi Aravind,

Yes, this reference design can be used. In TIDA-01527, the Resolver feedback Sine and Cosine signals are converted to single ended signals before feeding back to the MCU. So please ensure to select correct modes as per Section 7.5.3.2.2.1.1 Sequencer and RDC Modes of Operation of AM263Px Sitara Microcontrollers Technical Reference Manual (Rev. D). Please do note that the Resolver to Digital converter of AM263P can also take in Differential Sine and Cosine signals.

Please also refer to the reference circuit shown in Figure 7-147 of AM263Px Sitara Microcontrollers Technical Reference Manual (Rev. D), which shows a simpler implementation on the excitation signal side using ALM2403-Q1, in a single package.

Thanks,
Tejas Kulakarni
