Product details

MEMS oscillator for harsh environments

The DSC1101CM2-024.5454 is a MEMS-based XO (Standard) that outputs a 24.5454 MHz CMOS clock from a 2.25V to 3.6V supply rail.

±25 ppm stability across temperature

Frequency stability is rated at ±25 ppm over the full temperature range — tight enough to keep a UART baud-rate generator within tolerance without a TCXO. The MEMS resonator also eliminates the start-up settling time of a quartz crystal; the output is valid within microseconds of power-up.

Standby function for power-sensitive designs

A standby (power down) pin drops the supply current to 95 µA max when the clock is not needed. In a battery-powered sensor node that sleeps most of the time, that 95 µA standby draw is lower than the leakage of many LDOs — the oscillator does not dominate the sleep budget.

Product status is Active per Microchip. Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

What is the frequency stability of DSC1101CM2-024.5454?

±25 ppm over the full -55°C to 125°C range. That is tight enough for most precision timing without a TCXO.

Does DSC1101CM2-024.5454 have a standby (power down) function?

Yes. The standby pin reduces supply current to 95 µA max when the output is disabled.

Is DSC1101CM2-024.5454 a direct replacement for standard 24.5454 MHz quartz oscillators?

It is a drop-in replacement in terms of pinout and supply voltage (2.25V–3.6V), but the MEMS construction offers better shock/vibration tolerance and faster start-up than quartz. Confirm the footprint matches the 6-SMD, No Lead package (3.20mm x 2.50mm).

Can DSC1101CM2-024.5454 operate at 3.3V?

Yes. The supply range is 2.25V to 3.6V, so 3.3V is within spec.
