Product details

148.5 MHz MEMS clock for industrial timing

The MEMS resonator gives this oscillator better shock and vibration tolerance than a quartz crystal, plus a faster startup time — useful for video clocking, FPGA reference, or any board that sees mechanical stress.

Standby function and supply flexibility

A standby (power down) pin lets the system disable the output, dropping supply current from 35 mA max to 95 µA max — a meaningful power save for battery-operated or duty-cycled equipment. The supply voltage range spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator.

This part carries an Active product status. Supplied in Tape & Reel (TR) packaging, the 6-SMD no-lead footprint (3.20 mm x 2.50 mm) is a standard 6-pin oscillator layout, compatible with common pick-and-place and reflow profiles.

Frequently asked questions

Is DSC1101CI2-148.5000T a direct replacement for quartz oscillators?

Yes, in most applications. The DSC1101CI2-148.5000T is a MEMS-based oscillator with the same 6-SMD footprint and CMOS output as a standard quartz XO. The MEMS resonator offers better shock/vibration tolerance and faster startup, but the electrical interface (enable/standby pin, supply range, output drive) is designed to be a drop-in replacement for quartz oscillators of the same frequency and package.

What is the standby (power down) function of DSC1101CI2-148.5000T?

The standby (power down) function disables the output and reduces supply current from 35 mA max to 95 µA max. It is controlled by a dedicated pin — pulling it low puts the oscillator into standby; pulling it high or leaving it floating enables normal operation. This is useful for power gating in battery-powered or intermittent-duty systems.

Can DSC1101CI2-148.5000T be used in industrial temperature range?

This makes it suitable for outdoor telecom, factory automation, engine-bay electronics, and similar environments where the ambient temperature can swing below freezing or above 70°C.
