Product details

100 MHz MEMS clock with AEC-Q100 grade

The DSC1121BE2-100.0000T is a 100 MHz XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to +70°C operating range.

Manufactured by Microchip Technology under the DSC1121 series base part number. Availability confirmed at RFQ.

Housed in a 6-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a compact footprint that fits dense ECU or infotainment PCB layouts. Surface-mount only, no through-hole variant. Supplied on Tape & Reel, consistent with automated pick-and-place assembly.

Frequently asked questions

Is DSC1121BE2-100.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability stress tests. It is suitable for cabin and chassis-domain applications within its -20°C to +70°C operating temperature range.

What is the closest pin-compatible alternative to DSC1121BE2-100.0000T?

No official pin-compatible alternative is listed by Microchip for this specific frequency and package. The base part number DSC1121 covers a family — confirm the frequency, stability, and supply voltage match before substituting any sibling order code.

What is the output type and frequency of DSC1121BE2-100.0000T?

It is a 100 MHz XO (Standard) with CMOS output. The CMOS logic level follows the supply voltage rail (2.25 V – 3.6 V), so the high-level output swings rail-to-rail.
