Is it possible to use OMAP-L137's eHRPWM for digital input class D power amplifier

Other Parts Discussed in Thread: OMAP-L137

Hi,

    I checked the document for OMP-L137, and there are eHRPWM module in this chip. We want to build a class D amplifier and output signal was from OMAP-L137. Is it possible to use the eHRPWM to generate the PWM signal as the input of digital input power amplifier , for example TAS5612? 

   Thanks

Xiaoka

    I have worked on this issue for around 1 month, and we can use the eHRPWM to generate the PWM signal as the input of digital input power amplifier. I have tested it with real 4G OFDM signal, and the MEP size need to be calibrated.

    Thanks.
