Dear Sir,

Our customer want to adjust Rset and Rload value to meet TV output level 1.6V.

Could you help check how adjust  Rset and Rload value.

Thanks a lot,

We found Table 82 on i.MX6CEC.pdf Rev.6 10/2012

chapter 4.7.8.6.1 TV Encoder Performance Specification

Rset = 1.05 kΩ ±1%, resistor on VREFOUT pin to Ground

Rload = 37.5 Ω ±1%, output load to Ground

Full scale output voltage type=1.35V  and MAX=1.45V

Hi Andy

this module is characterized only under conditions

given in Table 82 of Datasheet. So other output voltages are not guaranteed.

Sorry, seems one needs to add some external circuits for boosting output

voltage.

Best regards
