Description
The SR-A2A70 Series
of quartz crystal oscillators provide Differential Sine Wave signals.
This device is to operate using positive voltage and uses multiple ground pins for improved
signal integrity.
Recommended Board Layout
Dimensions shown in inches (mm).
The metallic center pad was designed for
mechanical support. Grounding of this pad is
optional. It measures 0.088 x 0.190 NOM
(2.24 x 4.83 NOM).
