For a 33 MHz clock, ±50 ppm translates to ±1.65 kHz of possible frequency error — well within the tolerance for UART baud-rate generation, SPI timing, and most MCU PLL reference inputs. The part includes an Enable/Disable function on a dedicated pin. Maximum supply current is 27 mA typical when active, which is modest for a 33 MHz CMOS oscillator. The 6-VDFN package measures 7.00mm x 5.00mm with a seated height of 0.90mm, fitting standard surface-mount assembly processes.","metaTitle":"DSC1221NI1-33M00000T MEMS XO 33 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1221NI1-33M00000T: MEMS-based XO, 33 MHz, CMOS output, ±50 ppm, 2.5V-3.3V, AEC-Q100, -40°C to 85°C.
