Product details

MEMS oscillator with standby power-down

The DSC1033BI2-025.0000T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon series, delivering a 25 MHz CMOS output from a 3.3 V supply rail.

Microchip lists the DSC1033BI2-025.0000T as Obsolete.

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 footprint for 25 MHz oscillators, compatible with automated pick-and-place.

Frequency stability and supply current

For a 25 MHz clock, ±25 ppm corresponds to ±625 Hz of jitter budget at the receiver. Typical supply current is 3 mA max during active operation, keeping the thermal load low in the 4-SMD package without requiring airflow.
