The absolute pull range (APR) of ±50 ppm is the frequency stability the output holds over that entire span — the number a timing engineer budgets before the downstream PLL or ADC jitter allocation. The CMOS output swings rail-to-rail, making it a direct drop into most MCU clock inputs, FPGA global clock buffers, or Ethernet PHY reference oscillators. Housed in a 6-VDFN with exposed pad, 7.00 mm × 5.00 mm footprint, 0.90 mm seated height. The pad also provides a low-inductance return path for the CMOS output, which helps contain high-frequency harmonic content on the supply rail. Tape & Reel (TR) packaging suits automated pick-and-place. Product status is Active. The DSC1121 series is Microchip's standard MEMS oscillator family; the DSC1121AM1-014.7456T is a current catalog number available through independent distribution.","metaTitle":"DSC1121AM1-014.7456T MEMS Oscillator","metaDescription":"Microchip DSC1121AM1-014.7456T MEMS XO, 14.7456 MHz CMOS output, ±50 ppm APR, -55°C to 125°C, 6-VDFN.
