| kpjamro:
What does it mean for a frequency divider (aka pre-scaler) to be "low noise? The output is stated as being "rectangular". The output wave form is attached. This is dividing 100 MHz down to 10 MHz. Is only phase noise relevant here? I cannot measure phase noise directly. Would a MDEV measurement be meaningful? Ken |
| Benta:
One can only guess, but it sounds a bit like a marketing pitch. 1: low noise input for low amplitude analog inputs. 2: low irradiated noise from the power supply lines. |
| eugene:
What could possibly go wrong at 100 MHz? :-DD |
| MegaVolt:
Low Noise = Low Jitter |

Comparateur or Schmitt has jitter, creating phase noise Jon |
