MEMS-based 16 MHz clock for automotive and industrial boards
The DSC1121BI1-016.0000T is a 16 MHz MEMS oscillator from Microchip's DSC1121 series, delivering a CMOS output with enable/disable control.
Frequency stability and supply tolerance for timing margin
With ±50 ppm frequency stability over the full temperature range, this oscillator holds tighter than a basic ±100 ppm quartz part — important for CAN bus bit timing or sensor sampling intervals where cumulative drift eats into the sampling window. The supply voltage spans 2.25V to 3.6V, so it runs off a 3.3V or 2.5V rail without an extra regulator.
Enable/disable function and current draw in shutdown
The enable/disable pin lets a system microcontroller gate the oscillator output, cutting supply current from 35 mA max to 22 mA max when the clock is not needed — useful for power-sensitive nodes that sleep between CAN wake-ups or sensor read cycles.
Active lifecycle – design-in ready
Microchip lists the DSC1121BI1-016.0000T as Active — no NRND or EOL notice. It is suitable for new designs and production builds.
