Product details

35.328 MHz MEMS XO — drop-in for quartz

The DSC1033BI1-035.3280T is a MEMS-based XO (Standard) that outputs a 35.328 MHz CMOS clock from a 3.3V supply rail. The MEMS resonator replaces the quartz crystal inside the package, so the pinout and footprint match a standard 5.0mm x 3.2mm 4-SMD oscillator — no board spin needed when swapping from a quartz XO. That covers outdoor telecom, motor-drive control boards, and factory-floor PLC modules without needing a separate temperature-compensation circuit.

Standby power-down and low draw

Active current is 3 mA typical at 35.328 MHz. For a battery-powered sensor node that sleeps most of the time, this one pin saves milliamps compared to gating the output externally.

Frequently asked questions

Is DSC1033BI1-035.3280T a drop-in replacement for standard quartz oscillators?

Yes. The package is a standard 5.0mm x 3.2mm 4-SMD no-lead footprint, and the output is CMOS — same pinout as a quartz XO. The MEMS resonator inside is the difference, not the interface. No board layout change is needed.

What is the standby function on DSC1033BI1-035.3280T?

The Standby (Power Down) pin disables the oscillator and puts the output into high-impedance. Supply current drops to 1 µA maximum. Releasing the pin restarts the MEMS resonator and the CMOS output within the start-up time specified in the datasheet.
