The DSC1121BI1-014.8946 is a MEMS-based XO (standard oscillator) from Microchip Technology's DSC1121 series, delivering a fixed 14.8946 MHz CMOS output with enable/disable function. The wide supply range of 2.25V to 3.6V lets it run off a 2.5V or 3.3V rail without a separate regulator, simplifying the power tree.
Housed in a 6-VDFN package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The VDFN package reflows well with a standard lead-free profile.
Both are in the same DSC1121 series and share the same 14.8946 MHz frequency, CMOS output, and 6-VDFN package. The 'BI1' vs 'AI1' suffix typically indicates a different stability or temperature grade — confirm the 'AI1' part's specs against the 'BI1' (±50 ppm, -40°C to 85°C) before substituting.
