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 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
