Circuit Schematic Ultrasound Detector IC1 LMC567 Phase-Locked Loop

Ultrasonic. - Here is Circuit Schematic Ultrasound Detector IC1 LMC567 Phase-Locked Loop. The LMC567 is a low power general purpose LMCMOS[tm] tone decoder which is functionally similar to the industry standard LM567. It consists of a twice frequency voltage-controlled oscillator (VCO) and quadrature dividers which establish the reference signals for phase and amplitude detectors. The phase detector and VCO form a phase-locked loop (PLL) which locks to an input signal frequency which is within the control range of the VCO.

  1. Olá, estou tentando montar este esquema acima para teste, mas não estou encontrando 2N391M NPN transistor. Tem cfomo substituir este transistor por outro similar?
