Supply voltage and frequency stability
Runs from a 2.25V to 3.6V supply, so it can share a 3.3V or 2.5V rail without a separate LDO. Frequency stability is ±50 ppm — tight enough for a 100BASE-T1 Ethernet PHY reference or a CAN-FD controller clock, but check the ppm budget if the application requires a precision time base for a GPS-disciplined oscillator.
Enable/Disable function and power budget
Listed as Active by Microchip. The DSC1121 base product number covers a family of MEMS oscillators; if a different frequency or stability grade is needed, the same package and pinout applies across the series.
