Quartz Voltage Controlled Crystal Oscillator Hc-49s 3.2 ~ 90 Mhz 

Quartz voltage controlled crystal oscillator HC-49S 3.2 ~ 90 MHz


Quartz voltage controlled crystal oscillator HC-49S 3.2 ~ 90 MHz

Crystal oscillator is divided into passive and active are two types of crystal. Passive and active crystal oscillator English name is different,
Passive crystal to crystal (crystal), 2 pins, small, need the help of the clock oscillation circuit to generate the signal;
Active Crystal called oscillator (oscillator). A 4-pin, larger.

Active crystal pin square distribution:
1, the square, the use of DIP-8 package, the RBI is 1 foot.
   1-NC; 4-GND; 5-Output; 8-VCC
2, rectangular, using DIP-14 package, the RBI is 1 foot.
   1-NC; 7-GND; 8-Output; 14-VCC
