Product details

54 MHz MEMS oscillator with ±25 ppm stability

The DSC1033AE2-054.0000T is a 54 MHz MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range.

The part is supplied on tape and reel (TR) for automated assembly, and the 4-SMD, no-lead exposed pad package (7.00 mm x 5.00 mm footprint) is a standard surface-mount form factor.

Typical supply current is 4 mA at 54 MHz, which is competitive with quartz oscillators of the same frequency and simplifies power budgeting in 3.3V rails.

Frequently asked questions

Is the DSC1033AE2-054.0000T a direct replacement for a quartz oscillator?

Yes, the MEMS-based DSC1033AE2-054.0000T is a drop-in replacement for a standard 54 MHz quartz XO with CMOS output, 3.3V supply, and ±25 ppm stability. The MEMS resonator provides better shock and vibration immunity than quartz, which can be an advantage in industrial or portable equipment.
