Product details

27.12 MHz MEMS oscillator for low-power timing

Supply current is 95 µA maximum, drawing from a 2.25V to 3.6V rail.

That means the oscillator starts up faster (sub-millisecond typical) and survives higher shock and vibration levels than a crystal can. The 6-SMD no-lead package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that drops onto the same pads as many quartz oscillators, so a board designed for a 7x5 mm crystal oscillator can often take this MEMS part without a layout change.

Frequently asked questions

Can DSC1101AE2-027.1200 replace a standard 27.12 MHz crystal oscillator?

Yes, if the existing board uses a 7.00 mm x 5.00 mm 6-pin SMD footprint with CMOS input. The MEMS oscillator is a drop-in replacement for many quartz XOs of the same size — same supply range, same output type. Confirm the enable/standby pin mapping on your current part; the DSC1101AE2-027.1200 uses a standby (power-down) function on one pin.

What is the function of the standby pin on DSC1101AE2-027.1200?

The standby (power-down) pin disables the output and puts the oscillator into a low-power state. When asserted, the output goes to high-impedance and the supply current drops to near-zero — useful for gating the clock in battery-operated equipment without a separate load switch.
