Product details

Supply voltage compatibility and power budget

Operates across a 1.8V to 3.3V supply range, which means it can be driven directly from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V system rail without an external level translator.

Package, footprint, and mounting

Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5x3.2 mm oscillator footprint that matches many quartz and MEMS oscillators, simplifying PCB layout reuse.

Frequency stability and timing margin

Frequency stability is specified at ±50 ppm over the full operating temperature range and supply voltage variation — this is the total tolerance a system designer must budget for clock jitter and drift in high-speed serial interfaces or precision timing loops.

For a second-source option within the same family, the base product number DSC1001 covers multiple frequency and stability variants.

Frequently asked questions

Is DSC1001BI1-125.0000 compatible with a 3.3V supply?

Yes. The supply voltage range is 1.8V to 3.3V, so it works directly on a 3.3V rail without any external regulation or level shifting.

Does DSC1001BI1-125.0000 have a direct replacement or equivalent part?

No official pin-compatible replacement is listed by Microchip. The DSC1001 series itself offers multiple frequency and stability variants under the same base product number DSC1001. For a same-frequency alternative, confirm the package (4-SMD, 5.0x3.2 mm), supply voltage range, and CMOS output — many quartz and MEMS oscillators in this footprint are functional equivalents but may lack the AEC-Q100 qualification.

What is the function of the standby (power down) pin?

The standby function disables the output and reduces current consumption to 15 µA max, allowing the oscillator to be gated off during system sleep modes while maintaining a fast wake-up time typical of MEMS devices.
