The Enable/Disable function lets the system shut down the oscillator output, dropping supply current from 58 mA to 22 mA. ## Supply voltage flexibility and power budget Maximum supply current is 58 mA when enabled; at 22 mA when disabled, the oscillator's contribution to the system standby budget is low. ## Package, footprint, and board integration The 6-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount assembly with standard reflow profiles; the MEMS die inside the package eliminates the quartz crystal's sensitivity to board flex and mechanical shock during rework or field vibration. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1122CL2-156.2500T MEMS Oscillator 156.25 MHz LVPECL -","metaDescription":"Active XO (Standard) MEMS oscillator, 156.25 MHz LVPECL output, ±25ppm stability, -40°C to 105°C, 6-SMD.
