Product details

The DSC1001AL5-050.0000 is a 50 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC stress qualification that covers temperature cycling, ESD, and latch-up.

Housed in a 4-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1001AL5-050.0000 uses a standard 4-pad land pattern common to many MEMS and quartz oscillators. The no-lead construction reduces parasitic inductance compared to a gull-wing leaded package, which helps maintain signal integrity on the 50 MHz CMOS output. Surface-mount assembly follows standard reflow profiles for 4-SMD components; no special bake-out or moisture sensitivity handling is required beyond the MSL level indicated on the reel label.

For volume commitments or scheduled releases, a blanket order can be placed to secure allocation.

Frequently asked questions

Is the DSC1001AL5-050.0000 AEC-Q100 qualified?

Yes, the DSC1001AL5-050.0000 carries AEC-Q100 ratings, meaning it has passed the automotive-grade stress tests for temperature cycling, ESD, and latch-up. This qualification is required for under-hood and chassis-domain electronic modules.

Does the DSC1001AL5-050.0000 support 1.8V operation?

Yes, the supply voltage range is 1.8V to 3.3V, so it operates directly on a 1.8V rail without an external level translator. The CMOS output swings rail-to-rail, compatible with 1.8V logic inputs.

What is the difference between MEMS and quartz oscillators for this part?

The DSC1001AL5-050.0000 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration tolerance (up to 50,000 g), faster start-up time, and smaller package options. Quartz oscillators may still be preferred for ultra-tight frequency stability below ±10 ppm or for very low phase-noise applications, but the DSC1001's ±10 ppm stability meets most automotive and industrial timing requirements.
