Product details

The DSC1001CE1-027.0000 is an active-production 27 MHz MEMS-based XO (Standard) from Microchip Technology, delivering a CMOS output from a 1.8V to 3.3V supply rail.

Supply range and standby power — sizing the rail and sleep budget

Operating from 1.8V to 3.3V, this oscillator can be powered from either a 1.8V or 3.3V supply without a level translator — simplifies the rail design when both voltages are present on the board.

Package and footprint — 3.2mm x 2.5mm 4-SMD no-lead

Housed in a 4-SMD no-lead package measuring 0.126" x 0.098" (3.20mm x 2.50mm) with a seated height of 0.035" (0.90mm) — a compact footprint that fits tight PCB layouts common in automotive ECUs and portable equipment. Surface-mount mounting with no leads means the package sits flush on the board — no through-hole stubs to cause signal reflections at 27 MHz.

For extended industrial or under-hood use beyond 70°C, check the DSC1001 family's wider-temperature variants.

Frequently asked questions

How can I order DSC1001CE1-027.0000 or check stock?

No stock-holding claim; sourced through independent distribution per your request.

Is DSC1001CE1-027.0000 AEC-Q100 qualified for automotive use?

Yes, it is rated AEC-Q100, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin electronic modules where the ambient temperature stays within the -20°C to 70°C range.

What is the standby current consumption of DSC1001CE1-027.0000?

When the standby (power-down) function is enabled, the maximum disable current is 15µA. During active operation, the maximum supply current is 7.2mA.

Can DSC1001CE1-027.0000 replace a 27 MHz quartz oscillator?

Yes — it is a drop-in replacement for a 27 MHz quartz XO in the same 4-SMD no-lead footprint. The MEMS resonator offers faster startup, better shock resistance, and wider supply tolerance than a quartz equivalent, but the output frequency and CMOS logic levels are identical.
