Supply voltage spans 1.7V to 3.6V, covering 1.8V, 2.5V, and 3.3V logic rails without a separate LDO. The 105°C ceiling gives margin above the typical cabin limit.
Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm, seated height 0.90 mm max. The base product number DSC1003 covers the series; the DL2 suffix encodes the specific frequency, stability, and output option.
Product status is Active per Microchip.
Yes, it carries AEC-Q100 rating. This covers the automotive-grade qualification including temperature cycling, ESD, and reliability stress per the AEC-Q100 test flow. Suitable for under-hood and cabin ECUs.
Functionally yes — it provides the same 50 MHz CMOS clock. The MEMS resonator offers better shock and vibration tolerance than quartz, and the supply range is wider. Pinout and footprint (4-SMD no-lead) are standard for this class; confirm the land pattern matches your PCB layout.
The DSC1003 series is the AEC-Q100 qualified variant of the DSC1001. Both share the same MEMS resonator core and CMOS output. The DSC1003 adds automotive-grade qualification (temperature range, reliability stress) and is the recommended choice for automotive BOMs.
