Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The 0.50 mm pitch land pattern is standard for 2.0 x 2.5 mm oscillators — no exotic footprint, no tombstoning risk if the reflow profile is set for the 260 °C peak typical of lead-free solder. Supply voltage range is 1.8 V to 3.3 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator.
Yes, it includes an Enable/Disable pin. When disabled, the supply current drops to 15 µA max, allowing the system to gate the clock for low-power sleep states.
No. Because this is a MEMS oscillator (not a quartz crystal), the output is a full-swing CMOS clock that does not need external load capacitors. It is a self-contained clock source.
Other members of the Microchip DSC1001 series with the same 4-SMD no-lead footprint and 44 MHz frequency are direct pin-compatible substitutes. The key difference is frequency stability grade — the DI5 suffix specifies ±10 ppm. A ±25 ppm variant (e.g., DSC1001DI2-044.0000) would fit the same board if the application can tolerate wider stability.
