Product details

Obsolete – sourcing through surplus channels

Available through independent surplus distribution in lot-specific quantities.

50 MHz MEMS oscillator with standby mode

A MEMS-based XO (standard) delivering 50 MHz CMOS output from a 3.3V supply rail. The standby (power-down) function drops supply current to 1 µA max, making it suitable for battery-powered equipment that spends most of its life asleep.

Package and board layout

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch pads require standard SMD reflow assembly; no via-in-pad needed.

Frequently asked questions

Is the DSC1033CE2-050.0000T pin-compatible with the DSC1001 series?

Both are 4-pin MEMS oscillators in similar 3.2 x 2.5 mm SMD packages, but the evidence does not confirm direct pin compatibility. Verify the pinout against your PCB footprint before substituting.

What is the standby mode current of the DSC1033CE2-050.0000T?

When the standby function is asserted, the supply current drops to 1 µA max. This is the disable current, suitable for power-gating the oscillator in battery-operated designs.
