The DSC1121AE5-005.2500T is an active-production MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 5.25 MHz CMOS output with ±10 ppm frequency stability across its -20°C to 70°C operating range. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V, 3.0 V, and 3.3 V logic rails without a separate regulator — one BOM line serves multiple system voltage domains.
Housed in a 6-VDFN exposed pad package measuring 7.00 mm x 5.00 mm x 0.90 mm seated height.
The Enable/Disable pin allows the output to be tri-stated. When disabled, the supply current drops from 35 mA max to 22 mA max, reducing power consumption in idle or sleep modes.
