Output is CMOS, which means it drives the clock input of most MCUs, FPGAs, and Ethernet PHYs directly without an external level translator — the 1.8V to 3.3V supply range lets it straddle mixed-voltage boards where the core logic runs at 1.8V and the I/O bank at 3.3V.
The Standby (Power Down) function pulls the output to high-impedance and drops the supply current to 15 µA max — compared to the 7.2 mA max active current, this saves 99.8% of the oscillator's draw when the system sleeps. A battery-backed telematics unit that wakes once per minute to transmit a GPS fix spends 59 seconds in standby per cycle, making the disable current the dominant term in the sleep-state power budget.
Package, footprint, and sourcing posture
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — this is the standard 3.2 x 2.5 mm oscillator footprint shared by many MEMS and quartz XOs, so a board laid out for a SiTime or Abracon part in the same package will accept this Microchip device without a pad change. Product status is Active, meaning the factory continues to manufacture and support the DSC1001 series.
