Product details
Frequently asked questions
Is the DSC1001CI2-037.1250T qualified for automotive use?
Yes, it carries AEC-Q100 rating, meeting the reliability and temperature requirements for automotive applications such as engine control or infotainment modules.
Can the DSC1001CI2-037.1250T replace the DSC1001CI2-037.1250?
The base product number is DSC1001; the suffix 'T' indicates tape-and-reel packaging. The bare DSC1001CI2-037.1250 without 'T' is the same oscillator in a different packaging format – electrically identical. Confirm your BOM's packaging requirement before substituting.
Is the DSC1001CI2-037.1250T compatible with 3.3V logic?
Yes. The supply voltage range is 1.8V to 3.3V, and the CMOS output is rail-to-rail, so it interfaces directly with 3.3V logic families without level translation.
What is the difference between MEMS and quartz oscillators?
MEMS oscillators like the DSC1001 use a silicon micro-electromechanical resonator instead of a quartz crystal. They offer smaller footprint, higher shock/vibration tolerance, and faster startup, while quartz typically provides lower phase noise. For this part, the MEMS approach enables the 4-SMD no-lead package and the wide supply range.
