Low-noise frequency divider

(1/2) > >>

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?

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

jonpaul:
Comparateur or Schmitt has jitter, creating phase noise
