342 Oscillators II

342 : Oscillators II

Design render
  • Author: Mikhail Svarichevsky
  • Description: Free-running oscillators to verify simulation vs reality + TRNG
  • GitHub repository
  • Clock: 1000000 Hz

How it works

Combinational loops with dividers to bring output frequency to <50kHz range

How to test

Select oscillator (pins 4-6) and mesaure frequency on one of output pins. Observe true random numbers at pin 7.
