CRYSTAL CLOCK OSCILLATORS
Frequency Selectable Differential Sine Wave
Data Sheet 0549B
Rev. B
SY-A6A70 Series
Description
The
SY-A6A70 Series
of quartz crystal oscillators provides a Frequency Selectable Differential Sine Wave
signal. The oscillator frequency is set by the voltage applied to the frequency select pin. The two selectable
frequencies can be any discrete frequency selected within the range listed below. This device is to operate
using positive voltage and uses multiple ground pins for improved signal integrity.
Features
