The DSC1121NI1-025.0000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a fixed 25 MHz CMOS output. The Enable/Disable function on pin 1 lets the system pull the output to high-impedance, dropping supply current from 35 mA to 22 mA — useful for power-conscious designs that gate the clock during sleep modes.
The supply voltage spans 2.25V to 3.6V, so it runs from a 3.3V or 2.5V rail directly — no external regulator needed. The 6-SMD no-lead package (7.00mm x 5.00mm) is a standard footprint for 25 MHz oscillators, and the 0.90mm seated height fits low-profile enclosures.
Microchip lists the DSC1121NI1-025.0000 as Active.
