Its 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails directly, eliminating the need for a separate level translator on the oscillator supply.
The Enable/Disable function allows the output to be tri-stated, dropping the supply current from a maximum of 35 mA in active mode to 22 mA when disabled.
Sourced through independent distribution; quoted to order against the BOM quantity.
Yes. The supply voltage range of 2.25V to 3.6V includes 3.3V, and the CMOS output swings rail-to-rail, so it interfaces directly with 3.3V logic inputs without external level shifting.
The DSC1121AI2 and DSC1121BI2 share the same MEMS resonator, output type, and package. The difference is in the frequency stability grade: the AI2 variant is specified at ±25 ppm, while the BI2 variant offers tighter stability. Confirm the stability requirement for your timing budget before substituting.
