Product details

The supply voltage spans 2.25V to 3.63V, so it can run from a 2.5V or 3.3V rail without a separate LDO—handy when the MCU's core and I/O share a single regulator.

Frequency stability and supply current at the board level

That is tight enough for a 100BASE-T1 Ethernet PHY or a CAN-FD controller where bit timing margin depends on the reference accuracy. Maximum supply current is 27 mA typ when enabled, and 23 mA typ when disabled—the disable current is still high enough that a simple load switch ahead of the oscillator saves more power than relying on the enable pin alone in a sleep-mode design.

Package footprint and layout consideration

The 6-VDFN package measures 5.00mm x 3.20mm with a seated height of 0.90mm max. The 0.197" x 0.126" footprint matches the industry-standard 5x3.2 mm oscillator land pattern—no via-in-pad required, but a solid ground pour under the package helps with thermal and EMI. Surface-mount on tape and reel (TR) packaging is standard for automated assembly.

Frequently asked questions

Is DSC1221BL2-25M00000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up.

What is the frequency stability of DSC1221BL2-25M00000T?

Frequency stability is ±25 ppm, which keeps the output within 625 Hz of 25 MHz over the full operating temperature and voltage range.
