12MHz 4 Pin Crystal Oscillator Clock CO-34A1 20.3×12.7mm

20 Mhz frequency Load capacitance: 20pF. Frequency tolerance: +/-20 ppm Best for micro-controller based projects done in school and colleges. Works best with any kind of micro-controllers. Standard frequency crystals – use these crystals to provide a clock input to your microprocessor. It provide clock pulses of 20 Mhz frequency. It can be used as UART clock. It allows integer division to common baud rates (96?115200 baud or 96?96?1,200 baud). It is a common clock for AVR microcontroller It uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. Load capacitance: 20pF. Frequency tolerance: +/-20 ppm. Color: Silver
