That frequency is a common multiple for T1/ telecom rates and audio sample clocks — it divides cleanly to 8 kHz or 48 kHz without a PLL. ## Standby function for power-sensitive designs The 1 µA disable current is the leakage floor through the MEMS die and the CMOS output buffer — no external load switch needed to disconnect the oscillator during sleep. ## Industrial temperature range and frequency stability For a 12.288 MHz clock, ±50 ppm keeps the timing error within one bit period at common serial data rates. Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The DSC1033 family is Microchip's current MEMS oscillator line; the DI1 suffix denotes the 3.3 V supply and the ±50 ppm stability grade.","metaTitle":"DSC1033DI1-012.2880 MEMS Oscillator 12.288 MHz CMOS 3.3V -","metaDescription":"DSC1033DI1-012.2880 XO (Standard) MEMS oscillator, 12.288 MHz, CMOS output, 3.3V, ±50ppm, -40°C~85°C, 4-SMD.
