Crystal oscillator

Quartz Oscillator 3225 20M OSC

The Cd4093 consists of four 2-input Schmitt trigger circuits. Each circuit is a 2-input NAND gate with Schmitt trigger function on both inputs. Each gate opens and closes at a different point on the rising and falling edges of the signal. The difference between the rising voltage (V _P )T and the falling voltage (V _N ) is defined as the hysteresis voltage
(â–³V _T ).

The circuit is mainly composed of a four-two input NAND gate integrated circuit CD4093. A NAND gate (1, 2, 3, IC1) of R1, C1 and CD4093 constitutes a 400Hz square wave oscillator, and the square wave of the oscillator output is divided into two paths: one way is directly sent to a NAND circuit (4, 5) , 6 feet, IC2); the other way is sent to a NAND gate (8, 9, 10, IC3) via a capacitor C2. Since IC2 is connected in the form of a NOT gate, its input and output potentials are 180° out of phase, and the signal output from IC2 is coupled to the other input of IC3 via C3 and C4.
Since the levels of the two inputs of IC3 are the same. The phase is opposite, so as long as IC1 oscillates normally, at least one of the two inputs of IC3 is at a low level, so the output of IC3 is a stable high level. Due to the action of C6, VT1 is turned off. However, if the input signal of any input of IC3 is canceled or the amplitude of the signal is lowered below the input start level of the gate, IC3 outputs a square wave signal.
When a conductor approaches the sensing electrode, part of the signal coupled by C2 to the input pin 9 of IC3 is shunted to ground. If the amplitude of the signal after shunting is lower than the threshold level of the NAND gate, IC3 The square wave signal is output. After the signal is rectified by VD1 and VD2, the switching tube VT1 is turned on, and the power of the relay is turned on to make it close.
Capacitor C4 is the sensitivity adjustment capacitor. If the circuit needs to work with maximum sensitivity, you can adjust C4 to make the relay just pick up, then adjust C4 to make the relay just disconnect, then seal C4 with high frequency wax or insulating paint. .
