69.12 MHz MEMS oscillator — why drop the quartz
The DSC1033DI1-069.1200T: This is a MEMS-based XO (Standard) running at 69.12 MHz with CMOS output — the base resonator is a silicon MEMS structure, not a quartz crystal, which eliminates the shock/vibration failure mode and the frequency drift from crystal aging over the first year. The 4-SMD no-lead package (2.50 mm x 2.00 mm) is the same footprint as a standard quartz oscillator — no board layout change required when swapping from a crystal-based part.
The standby (power down) function drops supply current to 1 µA max when disabled — the active draw is 4 mA typ at 69.12 MHz. For a battery-powered sensor logging once per minute, the 1 µA standby current extends shelf life past the battery's self-discharge floor.
Rated -40°C to 85°C with ±50 ppm frequency stability — this covers outdoor telecom cabinets, factory-floor automation, and under-hood electronics where a commercial-grade oscillator would drift out of spec above 70°C. Single 3.3V supply rail — no separate core or I/O voltage needed, which simplifies the power tree for a 3.3V-only system.
