Product details

Lifecycle status is Active — no last-time-buy window, no PCN for discontinuation. This part is production-current and suitable for new designs today.

The supply range spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an intermediate regulator. A 3.3V system can run this oscillator directly — confirm the supply tolerance at the BOM level.

Housed in a 6-VDFN package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. No hand-solder rework profile needed; the VDFN package reflows with standard lead-free solder paste.

Frequently asked questions

Can DSC1101CI2-133.0000T be used in a 3.3V system?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec — no level translator or separate regulator is needed for the oscillator itself.

What is the frequency stability of DSC1101CI2-133.0000T?

The frequency stability is ±25 ppm. This is a standard stability grade for Ethernet and general-purpose clocking — adequate for most 100BASE-TX and Gigabit Ethernet reference designs, but verify jitter budget against your PHY's requirements.
