Output is CMOS, so it drives the clock input of an MCU, FPGA, or Ethernet PHY directly without a level translator. The Enable/Disable function lets the system shut the oscillator off when the clock tree is idle, dropping supply current from 35 mA to 22 mA. ## Active production — no LTB risk The DSC1121 series is a current product family; new designs can commit to this order code without a last-time-buy contingency. ## Supply voltage tolerance and board-fit Packaged in a 6-VDFN with exposed pad, 7.00 mm x 5.00 mm footprint, 0.90 mm seated height.","metaTitle":"DSC1121AL5-012.0000T MEMS Oscillator 12 MHz CMOS - Microchip","metaDescription":"DSC1121AL5-012.0000T XO (Standard) MEMS oscillator, 12 MHz CMOS output, ±10ppm stability, -40°C~105°C, 6-VDFN.
