Product details

100 MHz LVPECL MEMS oscillator for high-speed clock trees

Supply range and enable/disable for shared rails

The 2.25V to 3.6V supply range lets this oscillator run from a 2.5V or 3.3V rail without a dedicated regulator. The Enable/Disable pin (tri-level: high = output, low = high-Z, float = output via internal pull-up) simplifies power sequencing — the disable state draws 22 mA max, so the clock can be gated at the source rather than with an external buffer.

The DSC1122 series is a mature MEMS oscillator family with multiple frequency and stability variants sharing the same 6-SMD footprint — a BOM change to a different DSC1122 frequency or stability grade requires no board layout revision.

Frequently asked questions

Is the DSC1122BI2-100.0000T compatible with a 3.3V supply?

Yes. The supply range is 2.25V to 3.6V, so a 3.3V rail is within the operating envelope. The LVPECL output swing scales with Vdd — at 3.3V the differential swing is approximately 800 mV, which meets the LVPECL input threshold of most receivers.

Does the DSC1122BI2-100.0000T support the enable/disable function?

Yes. The Enable/Disable pin is standard on this part. Driving the pin low disables the output (high-Z state), reducing supply current from 58 mA max to 22 mA max. The pin has an internal pull-up, so leaving it floating enables the output by default.
