Product details

MEMS oscillator replacing a quartz crystal

The DSC1033DI2-007.3728 is a MEMS-based XO (Standard) that outputs a clean 7.3728 MHz CMOS clock directly — no external load capacitors or crystal resonator needed. It runs from a single 3.3 V supply and draws 10 mA max while active; in standby (power-down) mode the supply current drops to 1 µA max, making it suitable for battery-powered equipment that needs to gate the clock tree.

Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs.

Frequently asked questions

Can I replace a 7.3728 MHz quartz crystal oscillator with DSC1033DI2-007.3728?

Yes, if the existing design uses a standard 7.3728 MHz oscillator module with CMOS output and 3.3 V supply. The DSC1033DI2-007.3728 is a drop-in MEMS replacement in a 4-SMD no-lead package — no external load capacitors are required. Confirm the footprint matches the 2.50 mm x 2.00 mm outline and the enable/standby pin function aligns with your circuit.

Does DSC1033DI2-007.3728 require external capacitors?

No. Because it is a MEMS oscillator (XO) with an integrated resonator and CMOS output stage, it does not need the load capacitors that a bare quartz crystal would require. Connect the supply, ground, and output — the standby pin can be tied high or driven by a GPIO to enable the output.
