You mention it at the very end, but any idea why a more complex (and presumably expensive) oscillator is used?
Maybe availability of the IC?
It seems strange unless there is a performance (e.g. voltage stability due to stray capacitance sensitivity) advantage. It's not like they're worried about IP or litigation.
- kens 6y agoThe different oscillator types have various tradeoffs, so maybe this more-complex design was better for this application, as you suggest. Since the circuit complexity is all on the integrated circuit, the cost difference is probably very small. My other theory when people make strange design choices is that patents might be involved.
- chiph 6y agoPossibly ease of manufacturing because you had fewer unique parts to make/keep track of. Also allows market segmentation, differentiated by the multiplier and whether the disable pin was connected.
