Product details

100 MHz LVDS MEMS oscillator with AEC-Q100 grade

The DSC1123BI1-100.0000 is a 100 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal, delivering LVDS output in a 5.0 mm × 3.2 mm 6-SMD no-lead package. The Enable/Disable function lets you gate the output for system power sequencing or test modes without removing the supply rail.

Supply voltage and current budget

Maximum supply current is 32 mA when enabled, dropping to 22 mA when disabled — the disable current is still present because the internal PLL and MEMS bias remain powered.

Product status is Active — Microchip continues to manufacture the DSC1123 series, so this part is available for both new designs and production replenishment without a last-time-buy deadline. The MEMS resonator construction means no quartz crystal to age or crack under mechanical shock — a practical advantage for automotive and industrial field-replaceable modules.

Frequently asked questions

Is the DSC1123BI1-100.0000 equivalent to a quartz oscillator?

Functionally yes — it produces a 100 MHz LVDS clock just like a quartz XO. The difference is the MEMS resonator: better shock and vibration tolerance, faster startup, and no quartz aging drift. If your existing board uses a 100 MHz LVDS quartz oscillator in a 5.0 mm × 3.2 mm 6-pin footprint, the DSC1123BI1-100.0000 is a drop-in replacement without a board spin.

Is the DSC1123BI1-100.0000 AEC-Q100 qualified?

Yes, the DSC1123BI1-100.0000 carries AEC-Q100 qualification. This means it has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up, and early-life failure rate) required for deployment in safety-related and mission-critical automotive systems.
