Crystal oscillator
HIGH-FREQUENCY CRYSTAL OSCILLATOR
SG-710 series
• Ceramic package with 1.5 mm thickness.
• Excellent shock resistance and environmental capability.
• Low current consumption due to use of C-MOS technology.
• Low current consumption by output enabled function (OE) or
standby function (ST).
