The 6-SMD no-lead package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. Surface-mount reflow follows standard JEDEC profiles; the no-lead construction reduces parasitic inductance compared to a gull-wing package. The Enable/Disable pin should be pulled high or low externally — leaving it floating risks an indeterminate output state.
The oscillator outputs a fixed 25 MHz clock.
Yes, it carries AEC-Q100 ratings, certifying automotive-grade reliability for under-hood and chassis applications.
Yes — it is a MEMS-based oscillator in the same 6-SMD footprint and output format (CMOS) as many quartz XOs. The MEMS resonator offers better vibration and shock resistance than quartz, but the frequency stability (±50 ppm,) is comparable to a standard quartz XO. Verify the supply voltage and Enable/Disable logic polarity match your existing design.
MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They are generally more resistant to vibration and mechanical shock, have faster start-up times, and are less sensitive to supply-voltage noise. The DSC1121NM1-025.0000T's MEMS base resonator delivers the same ±50 ppm stability as a typical quartz XO but with improved ruggedness across the -55°C to +125°C range.
