Product details

The DSC1121BM1-100.0000T: No official successor or cross-reference has been filed, so the BOM position is stable as-is.

AEC-Q100 Grade? The part is qualified — now check the grade

The OEM auditor will want the specific AEC-Q grade (0 or 1) from the full qualification report; the datasheet's ordering table usually states it.

Rated 2.25V to 3.6V — the oscillator runs directly off a 2.5V, 3.0V, or 3.3V rail without an intermediate LDO. This wide range absorbs rail ripple and tolerance without frequency shift, which simplifies the power distribution network in an ECU or sensor module.

Package and mounting — 6-SMD, no lead

The 6-SMD, no-lead package measures 5.00mm x 3.20mm with a seated height of 0.90mm. That is the standard 5.0 x 3.2 mm MEMS oscillator footprint — compatible with most 6-pin XO layouts. Surface-mount reflow per JEDEC MSL level on the reel label; no lead forming needed.

Enable/Disable function and CMOS output

CMOS output delivers rail-to-rail swings into standard CMOS loads without level translation.

Frequently asked questions

What is the supply voltage range of DSC1121BM1-100.0000T?

Design engineers need to ensure compatibility with their power rail; incorrect voltage can damage the oscillator.

Is DSC1121BM1-100.0000T AEC-Q100 qualified?

For automotive applications, this qualification is mandatory; missing it could lead to design rejection.

What is the output type of DSC1121BM1-100.0000T?

Output type (CMOS) determines logic level compatibility with downstream ICs; mismatch can cause signal issues.

Where can I buy DSC1121BM1-100.0000T?

Sourcing buyers need confirmed stock and reliable distributors to avoid delays in production.

DSC1121BM1-100.0000T datasheet and pinout?

Engineers require pinout details for PCB layout and function (e.g., enable/disable) to design the circuit correctly.

What is the price of DSC1121BM1-100.0000T in bulk?

Buyers need pricing to budget BOM costs and compare with alternatives for cost optimization.
