Product details

The DSC1033CI1-008.0000T: Quantities are sourced through independent surplus channels and confirmed at RFQ — no stock-holding claim is made here.

8 MHz MEMS oscillator for industrial clocking

This is a fixed-frequency MEMS-based XO (Standard) delivering an 8 MHz CMOS output from a 3.3 V supply rail. The Standby (Power Down) function drops supply current to 1 µA max when the enable pin is pulled low — a useful feature for battery-powered designs that need to disable the clock during sleep without removing the supply rail.

Package and footprint for PCB layout

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The 0.126" x 0.098" footprint matches the industry-standard 3.2 x 2.5 mm oscillator land pattern — no via-in-pad required, and the four pads (VDD, GND, Output, Enable) route easily on a two-layer board.

Frequently asked questions

What is the replacement for the DSC1033CI1-008.0000T?

No pin-compatible replacement is documented by Microchip. A functional replacement would require a different order code from the DSC1033 series or another MEMS oscillator family — confirm the package, supply voltage, and frequency before substituting.

What is the frequency stability of the DSC1033CI1-008.0000T?

This is the total frequency deviation including initial tolerance, temperature drift, and aging.

Can the DSC1033CI1-008.0000T be used with a 3.3 V supply?

Yes, the device is specified for a 3.3 V supply rail. The supply voltage is listed as 3.3 V, and the CMOS output swings rail-to-rail on that supply.
