Product details

MEMS oscillator at 20 MHz — AEC-Q100 qualified

The DSC1121NE5-020.0000T is a Microchip MEMS-based XO delivering a 20 MHz CMOS output with ±10 ppm frequency stability across -20°C to 70°C.

When disabled, the maximum supply current drops from 35 mA to 22 mA — useful for low-power sleep modes in battery-backed automotive modules or IoT gateways where every milliwatt counts. The supply voltage accepts 2.25 V to 3.6 V, covering the common 2.5 V, 3.0 V, and 3.3 V logic rails without an external regulator. The 6-SMD no-lead package measures 7.0 mm × 5.0 mm with a seated height of 0.90 mm — a standard footprint that reflows on a typical lead-free profile with no special pad geometry.

Active — no obsolescence concern

Microchip lists the DSC1121NE5-020.0000T as Active. The base product number DSC1121 covers the full family, so if a different frequency or stability grade is needed, the same package and pinout applies across the series.

Frequently asked questions

How does the DSC1121NE5-020.0000T compare to a quartz oscillator?

The DSC1121 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators are inherently more resistant to vibration and mechanical shock, and they do not exhibit the frequency drift from crystal aging that quartz does. The trade-off is that quartz can sometimes achieve tighter absolute initial accuracy, but the ±10 ppm stability of this part is sufficient for most automotive and industrial clock trees. For a direct quartz alternative in the same 7.0 mm × 5.0 mm footprint, look at Microchip's DSC1001 series (same package, same pinout) — the difference is the resonator technology, not the
