Product details

The DSC1033BI2-020.4800 is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 20.48 MHz CMOS output at 3.3V with ±25 ppm frequency stability.

Industrial temperature grade and low-power draw

Typical supply current is 3 mA — low enough that the clock does not dominate the power budget in a 3.3V rail.

Active lifecycle — no obsolescence watch

Listed as Active by Microchip.

4-SMD, No Lead package — footprint notes

Housed in a 5.00mm x 3.20mm 4-SMD, No Lead package with a seated height of 0.90 mm.

Frequently asked questions

Does DSC1033BI2-020.4800 have a standby or power-down function?

Yes, it includes a Standby (Power Down) function. When disabled, the supply current drops to 1 µA max, preserving battery life in sleep-mode applications.

What package does DSC1033BI2-020.4800 come in?

It is supplied in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90 mm. The footprint is compatible with standard XO land patterns of the same dimensions.
