The MEMS resonator provides faster startup and better shock/vibration tolerance compared to quartz-based oscillators, which matters for equipment subject to mechanical stress during transport or operation. In active mode, the maximum supply current is 5 mA typical — low enough that the oscillator's contribution to the board thermal budget is negligible even in a densely populated assembly. Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts without requiring via-in-pad for the centre pad. ## Frequency stability and supply rail Frequency stability is specified at ±50 ppm, which covers the full temperature range and supply variation — adequate for most serial communication links and processor clock inputs that do not require a TCXO-grade hold. The 3.3V supply rail is common in digital systems; no additional level translation is needed when interfacing with 3.3V logic families.","metaTitle":"DSC1033CI1-120.0000 MEMS Oscillator 120 MHz CMOS - Microchip","metaDescription":"DSC1033CI1-120.0000 XO (Standard) from Microchip PureSilicon™ series. 120 MHz CMOS output, 3.3V, -40°C to +85°C, standby function.

The pinout matches the standard 4-pin SMD footprint, so it can drop into the same PCB land pattern.
