MEMS XO at 12 MHz — fits a standard quartz footprint
The DSC1030BE1-012.0000: This is a MEMS-based oscillator, not a quartz crystal — the resonator is a silicon MEMS structure, which means it handles the shock and vibration of a field swap or a shipped product better than a quartz can. It delivers a 12 MHz CMOS clock from a 3 V supply, in a 5.0 mm × 3.2 mm 4-SMD no-lead package that matches the footprint of common quartz XOs. The standby (power-down) function drops the supply current to 1 µA max — useful for battery-powered gear that sleeps most of the time and wakes on an external event.
Rated -20°C to 70°C — the commercial temperature band. This oscillator is at home inside an office switch, a point-of-sale terminal, or a home appliance. It is not rated for the -40°C floor of an outdoor base station or an engine bay; if your BOM calls for that, you need the industrial-grade DSC1030 variant. Frequency stability is ±50 ppm over that range — tight enough for a UART baud-rate generator or a microcontroller main clock, but not for a precision GPS reference.
