CG-742N Random Binary Generator

Random binary generator is oscillator which can be output binary signal of random timing. It is possible to make white noise combination with lowpass filter.

Noise generator Pseudo random M series
Basic oscillation frequency Depends on an externally connected resistor or external clock of TTL level
 Gain Amplifier
Basic oscillation frequency range 0.5MHz to 5MHz (externally connected resistor) 5MHz max. (external clock)
Output TTL level or ±5V (no load)
Supply voltage ±15V
Dimensions 54.4 x 33.7 x 9.4 (mm), 40 pins Dual-in-line packager


OP-102 can be combined with DT-212D series to enable implementation of sinewave oscillator with the frequency set by a 3-digit BCD input.

Oscillation frequency range 1Hz to 100kHz
Eternally connected components are necessary in 100Hz or lower
