It delivers two independent CMOS clock outputs: 16 MHz on output 1 and 32 MHz on output 2.
The wide supply range of 2.25 V to 3.6 V means the oscillator runs directly off a 2.5 V, 3.0 V, or 3.3 V rail with no external LDO.
Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a 0.90 mm seated height, the DSC2311KI2-R0056T fits into space-constrained designs such as IoT modules and portable instruments.
It can replace a single 16 MHz quartz oscillator if your design also needs a 32 MHz clock — the DSC2311KI2-R0056T outputs both frequencies from one package. However, it is a MEMS-based oscillator with a different internal architecture than a quartz crystal; verify that the output drive strength, rise/fall times, and jitter are compatible with your load. The 6-VDFN footprint is not pin-compatible with a standard 4-pin quartz oscillator can.
Yes. The supply range is 2.25 V to 3.6 V, so 3.3 V is within spec. The CMOS output swing tracks the supply rail.
Yes. The function is Enable/Disable. When disabled, the maximum supply current is 23 mA.
MEMS oscillators (like this DSC2311) use a silicon micro-electromechanical resonator instead of a quartz crystal. They offer faster start-up, better shock/vibration tolerance, and typically a smaller footprint. The trade-off is that MEMS oscillators may have slightly higher phase noise than a high-end quartz oscillator, but for most digital clocking applications the difference is negligible.
