Product details

27.12 MHz MEMS oscillator with ±25 ppm stability

The DSC1101AE2-027.1200T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a 27.12 MHz CMOS output with ±25 ppm frequency stability across its operating range. The standby (power-down) function lets you shut off the output when the clock isn't needed, saving further power in sleep modes.

No official successor or pin-compatible alternative is listed; the DSC1101 series covers a range of frequencies and stabilities, but this exact order code is the current production variant.

Surface-mount footprint and temperature grade

Housed in a 6-SMD, no-lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, it's a standard oscillator footprint that reflows easily with typical lead-free profiles.

Frequently asked questions

What is the frequency stability of the DSC1101AE2-027.1200T?

The frequency stability is ±25 ppm across the operating temperature range and supply voltage variation. That's tight enough for USB, Ethernet, and most microcontroller clock inputs without external trimming.

Does the DSC1101AE2-027.1200T have an enable or standby pin?

Yes, the device includes a standby (power-down) function. When the enable pin is pulled low, the output goes high-impedance and the supply current drops to near zero, which is handy for battery-operated gear that needs to sleep the clock tree.

What is the closest pin-compatible alternative to the DSC1101AE2-027.1200T?

Within the DSC1101 series, other frequency and stability variants share the same 6-SMD footprint and pinout. For a direct drop-in at a different frequency, look for other DSC1101 parts with the same package code. No second-source manufacturer is listed, so stick with Microchip for guaranteed compatibility.
