The DSC1121CI2-066.6667 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 66.6667 MHz CMOS output with enable/disable function.
Supply voltage spans 2.25V to 3.6V, so it runs off a 3.3V or 2.5V rail without a separate regulator.
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm.
The evidence does not list a RoHS compliance status. Confirm with the datasheet or your Microchip contact before assuming compliance for a restricted-materials BOM.
Yes — it is a drop-in XO replacement. The MEMS resonator gives better shock and vibration tolerance than quartz, but the electrical interface (CMOS output, enable/disable, supply range) is the same. Verify the footprint matches your 6-SMD land pattern.
