Product details

MEMS XO at 55.333 MHz – automotive-grade timing

The DSC1001AI1-055.3330T is a MEMS-based XO (Standard) from Microchip's DSC1001 family, delivering a fixed 55.333 MHz output in CMOS logic levels.

Supply range and standby power-down

Operating from 1.8V to 3.3V, the DSC1001AI1-055.3330T covers the three most common digital logic rails in a single BOM line — no need to stock separate 1.8V, 2.5V, and 3.3V oscillators for different voltage domains. For a battery-backed ECU or sensor module that spends most of its life asleep, the oscillator's own draw becomes negligible.

Package and board-mounting note

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 0.90 mm height fits within the clearance of most card-edge or mezzanine slot constraints.

Frequently asked questions

How can I order the DSC1001AI1-055.3330T or request a quote?

Submit an RFQ with your target quantity and target price; we confirm availability and current pricing at quote time. No stock-holding claim is made here — every order is quoted to your BOM line.

Is the DSC1001AI1-055.3330T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — and is suitable for use in automotive electronic modules without additional qualification.

What output type and package does the DSC1001AI1-055.3330T use?

Output is CMOS, compatible with standard digital logic inputs. The package is a 4-SMD, No Lead Exposed Pad, 7.00 mm x 5.00 mm, 0.90 mm seated height. The exposed pad must be soldered to the PCB thermal land.

Does the DSC1001AI1-055.3330T have a standby or power-down mode?

Yes, it has a Standby (Power Down) function. When the enable pin is driven low, the oscillator stops and draws 15 µA max, allowing the system to cut clock power during sleep states.
