Frequently asked questions
What is the frequency tolerance of DSC1030BI1-125.0000?
This is the total variation including temperature, supply voltage, and aging — budget this into your timing margin for 125 MHz clock distribution.
Does DSC1030BI1-125.0000 have a standby mode pin?
Yes, the part includes a Standby (Power Down) function. When the pin is asserted, the output is disabled and the supply current drops to 1 µA max, allowing the oscillator to be gated off in low-power system states.
Is DSC1030BI1-125.0000 compatible with a 3.3 V supply?
No — the specified supply voltage is 3 V. Operating at 3.3 V exceeds the rated range and may affect frequency stability or damage the internal MEMS circuitry. Use a 3 V rail or a regulator.
