Product details

Active MEMS oscillator at 24 MHz — sourcing and fit

The DSC1033BE1-024.0000T is an active-production MEMS-based XO from Microchip, delivering a 24 MHz CMOS output from a 3.3V rail. Its standby function drops supply draw to 1 µA, which matters for battery-powered equipment that spends most of its life asleep — a sensor node or portable instrument that wakes on an interrupt doesn't waste power on the clock tree during idle periods.

3 mA typical draw and standby power-down

At 3 mA typical, the active current is low enough that the oscillator isn't the dominant term in the system power budget — the MCU core or radio will draw an order of magnitude more. The standby current of 1 µA means the oscillator can be left powered on the rail and disabled via the standby pin, avoiding a separate load switch.

Housed in a 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits the standard 5x3.2 mm footprint common to many MEMS and quartz oscillators.

Frequently asked questions

Is DSC1033BE1-024.0000T RoHS compliant?

The evidence does not list a specific RoHS compliance statement, but as a current-production Microchip part in a standard 4-SMD package, it is expected to meet RoHS requirements. Confirm with the datasheet or your compliance team for formal certification.

Can DSC1033BE1-024.0000T replace other 24 MHz oscillators like ASFLM1-24.000MHz?

The DSC1033BE1-024.0000T is a MEMS-based XO with a 3.3V supply, CMOS output, and standby function. The ASFLM1-24.000MHz is a quartz-based oscillator — check pin compatibility, supply voltage, and enable logic before substitution. The MEMS construction offers better shock and vibration tolerance, which may be an advantage in portable or ruggedized designs.

What is the standby power-down current of DSC1033BE1-024.0000T?

The standby (disable) current is 1 µA maximum, which is orders of magnitude below the active current and suitable for battery-powered sleep modes.

Can DSC1033BE1-024.0000T be used with a 2.5V supply?

The specified supply voltage is 3.3V. The evidence does not list a 2.5V operating range — using it outside the rated supply voltage is not supported. For a 2.5V rail, look at the DSC1033 family variants with a 2.5V option.
