CMOS output at 44.736 MHz directly drives the clock input of most MCUs, FPGAs, and Ethernet PHYs without an external level translator — the 35 mA max supply current at full load is within the budget of a 3.3 V rail. ## Supply range and frequency stability over temperature Operating from 2.25 V to 3.6 V, this oscillator spans both 2.5 V and 3.3 V logic families without a separate regulator — the Enable/Disable pin (E/D) pulls the output to high-impedance and drops supply current to 22 mA max, useful for power-sequencing or sleep modes. ## Package footprint and layout fit Housed in a 6-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, this oscillator fits on a 0.8 mm pitch BGA fan-out region or a dense multi-layer board — the no-lead construction eliminates side-solder inspection and reduces tombstoning risk during reflow.","metaTitle":"DSC1121DI5-044.7360 MEMS Oscillator – 44.736 MHz, CMOS","metaDescription":"Microchip DSC1121DI5-044.7360 XO (Standard) with MEMS resonator, 44.736 MHz CMOS output, ±10 ppm stability, 2.25-3.6 V supply, -40 to +85°C.
