Product details

The DSC1121CE2-066.6600T is a MEMS-based XO (Standard) oscillator delivering a 66.66 MHz CMOS output with ±25 ppm frequency stability across the full -20°C to 70°C range. The AEC-Q100 rating means this part passed automotive-grade reliability stress — a common requirement for engine-control modules, transmission controllers, and body electronics that see temperature swings and vibration.

Microchip lists the DSC1121CE2-066.6600T as Active.

6-SMD footprint and supply-range flexibility

The 6-SMD, No Lead package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts. The wide supply range (2.25 V – 3.6 V) allows the same BOM entry to serve multiple voltage domains, reducing line-item count.

Frequently asked questions

How can I order the DSC1121CE2-066.6600T or request a quote?

Submit your target quantity and delivery timeline — we confirm availability and current pricing at quote time, sourced through our independent distribution channel.

Is the DSC1121CE2-066.6600T AEC-Q100 qualified?

Yes, the DSC1121CE2-066.6600T is rated AEC-Q100, which means it passed automotive-grade IC qualification including temperature cycling, ESD, and reliability stress. It is suited for under-hood and cabin electronics where the ambient temperature stays within -20°C to 70°C.

What is the output type and supply voltage range for this part?

The output is CMOS, compatible with standard digital logic inputs. The supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an extra regulator.
