Product details

45.1854 MHz MEMS XO with wide supply tolerance

The DSC1101CE5-045.1854 is a 45.1854 MHz MEMS-based oscillator (XO) with CMOS output, operating from a 2.25V to 3.6V supply rail — a single part covers 2.5V, 3.0V, and 3.3V logic without a separate regulator. The MEMS resonator gives this oscillator better shock and vibration tolerance than a quartz crystal, which matters if the board sees portable or industrial handling.

Standby power-down and commercial temperature grade

A Standby (Power Down) function drops the supply current to 95 µA max when the enable pin is pulled low — useful for battery-powered equipment that sleeps between active bursts. Rated for -20°C to 70°C, this is a commercial-temperature part suited to indoor electronics, office equipment, and appliance PCBs where the ambient stays within that band.

Frequently asked questions

Can I use the DSC1101CE5-045.1854 as a replacement for the DSC1101CE3-045.1854?

The DSC1101CE5 and DSC1101CE3 share the same base product number and 6-VDFN package, but the suffix indicates different temperature grades or options. Confirm the operating temperature range and supply voltage of your existing part against the -CE5 variant before substituting.
