Four-frequency MEMS clock source in 3.2×2.5 mm QFN
The DSC2010FI1-A0003T is a MEMS-based XO (Standard) from Microchip's DSC2010 family that outputs four factory-programmed frequencies: 25 MHz, 75 MHz, 125 MHz, and 150 MHz, selected via pin strapping. Output is LVCMOS with an Enable/Disable function, drawing 35 mA max from a 2.25–3.6 V supply rail — compatible with 3.3 V and 2.5 V logic domains without an external level translator. The 14-VFQFN exposed-pad package (3.20 mm × 2.50 mm, 0.90 mm height) suits dense PCB layouts where a single oscillator replaces four discrete crystal cans, saving board area and reducing BOM line count.
