Product details

MEMS oscillator at 74.25 MHz – CMOS output, 3.3V rail

The DSC1033CI2-074.2500T: This is a standard XO (Standard) MEMS oscillator from Microchip's DSC1033 PureSilicon™ series, delivering a fixed 74.25 MHz CMOS output from a 3.3V supply rail. The ±25 ppm frequency stability covers most video clock and serial data applications without external tuning.

Standby power-down and low active current

This makes the part suitable for battery-operated equipment that spends most of its life asleep but needs a precise clock on wake.

Industrial temperature range and 4-SMD package

The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that reflows with standard lead-free profiles.

Frequently asked questions

Is DSC1033CI2-074.2500T compatible with 3.3V systems?

Yes, the supply voltage is specified as 3.3V, and the CMOS output swings rail-to-rail, so it interfaces directly with 3.3V logic without level translation.

What is the footprint of DSC1033CI2-074.2500T?

The package is a 4-SMD no-lead, 3.20 mm x 2.50 mm body with a 0.90 mm seated height. The four pads are on the bottom — standard reflow layout; no through-holes.

Does DSC1033CI2-074.2500T have a standby power-down function?

Yes, the function is listed as Standby (Power Down). When enabled, the supply current drops to 1 µA max, and the output goes high-impedance.

How does DSC1033CI2-074.2500T compare to a quartz oscillator?

This is a MEMS-based oscillator, not a quartz crystal. It offers faster start-up, better shock/vibration tolerance, and a smaller footprint than a quartz oscillator at the same frequency. The ±25 ppm stability is comparable to a standard quartz XO.
