Product details

66.6666 MHz MEMS oscillator – fit and function

The DSC1030BI1-066.6666T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 66.6666 MHz CMOS output from a 3V supply rail.

Microchip lists the DSC1030BI1-066.6666T as Obsolete.

Housed in a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the oscillator occupies a standard 5×3.2 mm MEMS oscillator footprint. The surface-mount package reflows with standard lead-free profiles; no special via-in-pad or thermal pad is required.

Frequently asked questions

How can I order the DSC1030BI1-066.6666T or request a quote?

The DSC1030BI1-066.6666T is obsolete per Microchip. Submit a quote request with your target quantity and we will respond with lot-specific availability.

Is the DSC1030BI1-066.6666T compatible with a 3.3V supply?

No. The supply voltage is specified as 3V. Operating at 3.3V exceeds the rated voltage and may damage the oscillator or cause frequency drift. Use a 3V rail or a regulator to drop from 3.3V.

What is the output frequency of the DSC1030BI1-066.6666T?

The oscillator outputs a 66.6666 MHz CMOS signal. This frequency is commonly used as a reference for Ethernet PHYs, FPGAs, or MCUs requiring a precise 66.6666 MHz clock.
