CFG280 intermittent noisy sine output

Post by rumreich » October 23rd, 2016, 6:44 pm

My CFG280 has intermittent low-level noise in the sine output mode only. The noise seems to be digital in nature.

I found some schematics - and the noise is also present on TP30 (before the output driver circuitry).

Has anyone else experienced this problem and found a cause?

Thanks in advance for any help.
