Active production — MEMS oscillator for 120 MHz clocking
The DSC1033CI1-120.0000: This is a 120 MHz XO (Standard) oscillator built on a MEMS base resonator, delivering a CMOS output at 3.3V supply. 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.
