Product details

54.8352 MHz MEMS XO with CMOS output

The DSC1121AI3-054.8352 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 54.8352 MHz CMOS clock output.

The supply voltage range spans 2.25V to 3.6V, letting the oscillator run directly from a 2.5V or 3.3V rail without an external LDO. Maximum supply current is 22 mA when enabled.

6-VDFN package and surface-mount layout

Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AI3-054.8352 fits standard surface-mount reflow processes. The 0.276" x 0.197" footprint matches the common 7x5 mm oscillator land pattern.

Frequently asked questions

What is the output type of DSC1121AI3-054.8352?
