MEMS oscillator at 11.0592 MHz — what the specs mean for your board
The DSC1033DI1-011.0592T: The ±50 ppm frequency stability over -40°C to 85°C keeps UART baud rates and MCU clock dividers within tolerance across the industrial temperature band — no external crystal or tuning capacitors needed. For a battery-powered sensor logging data once an hour, the standby current is below the self-discharge floor of a typical coin cell — the oscillator isn't what drains the battery between wake cycles.
Microchip lists the DSC1033DI1-011.0592T as Obsolete. A board spin to a newer DSC1033-series variant or a different MEMS oscillator family is the migration path for new designs.
