Product details

The CMOS output swings rail-to-rail into standard logic inputs without level translation, and the wide supply range (2.25V to 3.6V) lets it run from either a 2.5V or 3.3V rail — no extra regulator needed for the oscillator itself. At 100 MHz, this part suits high-speed serial interfaces (Gigabit Ethernet, PCIe reference clocks) and processor core timing where a clean square wave and tight jitter budget matter.

Industrial temperature and stability

The 6-SMD, No Lead package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard 7x5 oscillator footprint that is pin-compatible with many quartz and MEMS oscillators in the same form factor. The 0.90 mm height keeps it low-profile for mezzanine or stacked-board assemblies.

Frequently asked questions

What is the datasheet for DSC1121NI1-100.0000T?
