Output is CMOS, so it drives a standard digital clock input directly; the supply range of 2.25V to 3.6V covers 2.5V and 3.3V rails without an external level translator.
Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the package fits a dense PCB layout; the 0.50 mm pitch pads require a standard NSMD land pattern with a via-in-pad only if the thermal pad is present.
Yes — the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within the operating envelope. The CMOS output swings rail-to-rail and drives a 3.3V clock input directly.
The DSC1121 series shares the same 6-VDFN package and pinout but offers a different feature set (enable/disable instead of standby). For a drop-in replacement with the standby function, stay within the DSC1101 series and select the same frequency and stability grade.
A MEMS resonator is less sensitive to vibration and shock than a quartz crystal, and it starts up faster — typically under 5 ms vs 10–20 ms for a quartz oscillator. The trade-off is that the phase-noise floor at close-in offsets (1 kHz to 100 kHz) can be higher than a good quartz design, which matters for a low-jitter ADC or PLL reference.
