Product details

100 MHz MEMS oscillator for industrial clock trees

The DSC1121DI5-100.0000: The MEMS resonator is inherently more resistant to shock and vibration than a quartz crystal, and it starts up faster — no crystal start-up time to budget into the power-on sequence.

Supply voltage and enable/disable control

It operates from a 2.25 V to 3.63 V supply, covering the common 2.5 V and 3.3 V logic rails without an extra regulator. The Enable/Disable function lets the system gate the clock output; when disabled the supply current drops to 22 mA max, useful for power-sensitive modes.

Frequently asked questions

Can DSC1121DI5-100.0000 replace a quartz crystal oscillator of the same frequency?

Yes, it is a drop-in functional replacement for a 100 MHz quartz XO with CMOS output, provided the board layout accommodates the 6-SMD no-lead package (2.50 mm x 2.00 mm footprint). The MEMS version offers better shock tolerance and faster startup, but the electrical interface — supply voltage, output type, enable polarity — must match the existing design.
