DS90UB941AS-Q1: PWM PASS THROUGH

Jiawei Hu1
Expert 6475 points

Part Number: DS90UB941AS-Q1

Hi team,

For 941 pairing with 940, can the PWM signal transfer through GPIO on forward channel? The PWM is 20Khz, and the requirement of delay won't more than 0.1%.

Thanks!

    Hi Jiawei,

    GPIO pins can be used to send a PWM signal from the SER to the DES. The maximum frequency of the PWM signal is defined in the AC Electrical Characteristics table in the UB941AS datasheet:

     

    Depending on the PCLK in your system and the single/dual configuration, then the allowable PWM frequency can be determined.

    Best,
