No official successor or direct replacement is cited in the available records. 1.8432 MHz is a standard baud-rate generator frequency — it divides cleanly to common serial rates like 115200 baud, making this oscillator a natural fit for UART clocking on MCU or FPGA designs. ±50 ppm frequency stability holds the clock within 92 Hz of 1.8432 MHz across temperature and aging — adequate for serial communication and general-purpose MCU clocks, but not for precision timing or RF carrier synthesis where ±25 ppm or better is typical. Max supply current of 3 mA typ and 1 µA in standby keep the power budget low — the disable function lets the system gate the clock when the downstream logic is idle, saving battery life in portable or remote equipment. 3.3V supply rail matches common MCU and FPGA I/O banks — no level translator needed when the oscillator feeds a 3.3V CMOS input. 4-SMD no-lead package, 3.20 mm x 2.50 mm body, 0.90 mm seated height.","metaTitle":"DSC1033CI1-001.8432T XO 1.8432 MHz CMOS MEMS Oscillator -","metaDescription":"DSC1033CI1-001.8432T XO (Standard) MEMS oscillator, 1.8432 MHz, CMOS output, 3.3V, ±50 ppm, -40°C to +85°C.
