The DSC6001JL3B-032.7680 is a MEMS-based XO (Standard) oscillator delivering a 32.768 MHz CMOS output with ±20 ppm frequency stability — the MEMS resonator gives it better shock and vibration immunity compared to a quartz crystal, and the footprint is smaller at 2.50 mm x 2.00 mm in a 4-VLGA package. Supply voltage spans 1.71V to 3.63V, which covers 1.8V, 2.5V, and 3.3V logic rails without an external regulator — useful when the same BOM position feeds different voltage domains across variants.
Why choose a MEMS oscillator over a quartz crystal for 32.768 kHz?
The MEMS construction eliminates the need for external load capacitors and provides faster start-up, lower jitter, and better long-term stability than a quartz resonator at the same frequency.
The base product number is DSC6001; other frequencies in the DSC60XXB series share the same 4-VLGA pinout, so a frequency change does not require a board layout revision.
