Maximum supply current is 22 mA at 131.072 MHz, which sets the power budget for the clock tree. ## Package footprint and board layout Housed in a 6-SMD no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint shared by many MEMS and quartz oscillators. The no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain signal integrity at 131 MHz.","metaTitle":"DSC1121BI2-131.0720 MEMS Oscillator 131.072 MHz CMOS -","metaDescription":"DSC1121BI2-131.0720 XO (Standard) MEMS oscillator, 131.072 MHz, CMOS output, ±25ppm stability, -40°C to 85°C, 2.25V-3.6V supply, 6-SMD.
