Product details

The DSC1121DE1-050.0000T is a 50 MHz MEMS-based XO (standard oscillator) from Microchip Technology, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range.

Supply voltage and output compatibility

CMOS output is the standard interface for most digital clock inputs; it swings rail-to-rail and is compatible with 3.3 V logic without additional termination, though the 35 mA max supply current should be budgeted in the power estimate.

Package, footprint, and sourcing posture

Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this is a compact footprint suitable for space-constrained PCBs — the no-lead construction reduces parasitic inductance compared to a gull-wing package.

Frequently asked questions

Is the DSC1121DE1-050.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up — suitable for under-hood or cabin environments where a commercial-grade oscillator would not be approved.

Can the DSC1121DE1-050.0000T replace a 50 MHz quartz crystal oscillator?

Functionally yes — it outputs a 50 MHz CMOS clock that can replace a quartz-based XO in the same socket, provided the supply voltage (2.25-3.6 V) and stability (±50 ppm) meet the downstream timing budget. The MEMS resonator is more shock-tolerant than quartz, which is a reliability advantage in automotive or industrial environments.
