Active MEMS oscillator at 120 MHz – what it replaces and where it fits
The DSC1033CI1-120.0000T: This is a MEMS-based XO (standard oscillator) from Microchip's DSC1033 PureSilicon™ series, delivering a 120 MHz CMOS output from a 3.3V rail.
Standby function and supply current – the power-down edge
Typical supply current is 5 mA when active, dropping to 1 µA max in disable — a meaningful power saving for battery-operated or intermittent-duty equipment where the clock tree can be gated.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead land pattern is standard for MEMS oscillators of this size — no via-in-pad required, and the small footprint frees board space on dense mixed-signal or multi-clock designs.
