Product details

The DSC1123CI2-050.0000T is a 50 MHz LVDS MEMS oscillator from Microchip's DSC1123 series. It delivers a standard XO function with an Enable/Disable pin, drawing 32 mA max from a 2.25 V to 3.63 V supply. The AEC-Q100 qualification (Grade 3 implied by the temp range) means it has passed the reliability stress tests for automotive ICs — a step beyond a standard commercial XO.

Package and footprint — 6-SMD, 3.2 mm x 2.5 mm

Housed in a 6-SMD, No Lead package measuring 0.126" x 0.098" (3.20 mm x 2.50 mm) with a seated height of 0.035" (0.90 mm). This is a standard 6-pad ceramic/plastic SMD footprint — no special via-in-pad or thermal pad requirements.

Frequently asked questions

What is the footprint of DSC1123CI2-050.0000T and is it compatible with standard 6-SMD?

The package is a 6-SMD, No Lead (6-pad) measuring 3.20 mm x 2.50 mm, 0.90 mm seated height. This is a standard 6-pad SMD oscillator footprint — no special layout requirements. It is compatible with any PCB land pattern designed for a 6-SMD MEMS or quartz oscillator of the same dimensions.

Is DSC1123CI2-050.0000T AEC-Q100 qualified?

Yes, the ratings field lists AEC-Q100 qualification. This means the device has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for deployment in automotive cabin and chassis domains where the ambient temperature stays within -40°C to 85°C.

Can DSC1123CI2-050.0000T replace a quartz oscillator in my design?

Yes, if the existing quartz oscillator is a 50 MHz LVDS XO in a 6-SMD package with the same pinout (Enable/Disable function) and supply voltage range (2.25 V to 3.63 V). The MEMS resonator offers better shock and vibration tolerance compared to quartz — a practical advantage in automotive and industrial environments. Confirm the output type (LVDS) and frequency stability (±25 ppm) match your timing budget.
