Frequency stability is ±50 ppm, which keeps the 40 MHz carrier within tight tolerance for UART baud-rate generation or Ethernet PHY reference clocks without external trimming.","metaTitle":"DSC1121DL1-040.0000 – 40 MHz MEMS XO, CMOS, 6-VDFN, Active","metaDescription":"Microchip DSC1121DL1-040.0000: 40 MHz MEMS oscillator, CMOS output, Enable/Disable, 2.25-3.6V, -40°C to 105°C, 6-VDFN.
