Its 3.3V supply and 3 mA typical current draw suit power-conscious designs in industrial control, telecom, and embedded systems where a quartz-free resonator reduces board-level vibration sensitivity. Microchip lists the DSC1033CI1-014.7456T as obsolete. Date-code provenance should be verified before committing to a production run. ## Industrial temperature and low-power profile ## 4-SMD no-lead package and tape-and-reel delivery","metaTitle":"DSC1033CI1-014.7456T MEMS Oscillator 14.7456 MHz Obsolete","metaDescription":"DSC1033CI1-014.7456T XO (Standard) CMOS output, 14.7456 MHz, ±50 ppm, -40°C to +85°C, 3.3V.
