At 50 MHz the max supply current is 35 mA; pulling the enable pin low drops it to 22 mA. Frequency stability is ±25 ppm, tight enough for a 100BASE-TX Ethernet reference or a high-speed ADC clock without external trimming.","metaTitle":"DSC1121BI2-050.0000 50 MHz MEMS Oscillator – Microchip","metaDescription":"Microchip DSC1121BI2-050.0000: 50 MHz XO, CMOS output, AEC-Q100, -40°C to 85°C, 2.25V–3.6V supply.
