Crystal oscillator
SOJ HIGH-FREQUENCY CRYSTAL OSCILLATOR
SG-615 series
• High-density mounting-type SMD.
• A general-purpose SMD with heat-resisting cylindrical AT-cut
crystal unit and allowing almost the same soldering temperature
as SMD IC.
• Cylindrical AT crystal unit builtin, thus assuring high reliability.
• Provided with output enable function.
• Low current consumption.
