Product details

12.288 MHz MEMS XO — industrial temp, standby power-down

A standard XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal, the DSC1033CI2-012.2880 delivers a fixed 12.288 MHz CMOS output from a 3.3V supply.

Microchip lists the DSC1033CI2-012.2880 as Obsolete. No official successor part number is published, but the DSC1033 series remains available in other frequency/temperature variants — a pin-compatible replacement with the same 4-SMD no-lead footprint and 3.3V supply can be selected from the active DSC1033 family.

Housed in a 4-SMD no-lead package measuring 0.126" × 0.098" (3.20 mm × 2.50 mm) with a seated height of 0.035" (0.90 mm). The small footprint suits space-constrained PCBs in portable or densely populated designs.

Frequently asked questions

How can I order DSC1033CI2-012.2880 or check stock?

The DSC1033CI2-012.2880 is obsolete and no longer in production. It is sourced through independent surplus channels — submit an RFQ with your target quantity and we will confirm availability and current pricing. No stock-holding claim is made; every order is quoted to order.

What is the direct replacement for DSC1033CI2-012.2880?

Microchip has not published a specific direct replacement. However, the active DSC1033 series includes other 12.288 MHz variants in the same 4-SMD no-lead package and 3.3V supply — for example, a ±25 ppm industrial-temperature part with the same standby function. Check the DSC1033 family datasheet for available order codes; the pinout and footprint are identical across the series.

Does DSC1033CI2-012.2880 support a standby power-down mode?

Yes. The function is listed as Standby (Power Down). When disabled, the supply current drops to 1 µA max, and the output goes high-impedance. This makes it suitable for battery-powered designs that need to conserve power between active periods.
