OPT8241: Can I change the modulation frequency?

Part Number: OPT8241
Other Parts Discussed in Thread: OPT9221

Hi,

1. Can I change the modulation frequency?

If yes, what is the range for the possible modulation frequency?

2. OPT8241 supports two modulation frequencies for resolving aliasing issue. Can I use only one modulation frequency?

Thanks

    Hi,

    Please refer to OPT9221 datasheet section 7.3.5 for understanding how to set modulation frequency. Section 7.3.7.2 describes how to enable and disable de-aliasing mode.
    Single frequency mode has 2 options of using 6 quads and 4 quads. 4 quads is the default with single frequency. Using 6 quads single frequency is described at the end of section 7.3.7.1 of OPT9221 datatsheet.
