Anyone tried an Analog2HDMI on CPC?

Hi,

Has anyone tried one of these on a CPC?

Is it similar in concept to the RGB2HDMI?

This is how the RGB2HDMI works with the CPC.

There is H sync Vsync separately.
Does it need to add H V sync separation?

It's more like the GBS8200 than the RGB2HDMI (which only takes digital input).

It's unclear if it can upscale 15.6kHz signals or if VGA means it needs a 31kHz signal for RGB. 

The GBS8200 accepts 15.6kHz and there is also a variant that outputs HDMI. However I haven't tried that yet. 

RGB2HDMI has several variants for different computers. The one for the CPC afaik uses analogue input, the one for the Plus (or Amiga/Atari) uses the digital signals at the DAC.

No it does not. There's a comparator circuit that detects the intermediate voltage level, but that's too crude to be considered a real ADC. 

Everything else is pretty much right. The analog2hdmi is more like the vga2hdmi that people plug into the back of the gbs8200 (it's late and I'm moving house, had a brainfart) so it's likely you'd still need a gbs8200 to get a signal the analog2hdmi can lock to anyway.

Not sure it will work, says VGA or component input which isn't what the CPC puts out
