The DSC1001AI1-048.0000T is a 48 MHz MEMS-based XO from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range.
In active mode the oscillator draws 7.2 mA max — a tight budget for always-on CAN transceivers or sensor interfaces that need a 48 MHz reference but can sleep between bus cycles.
No pin-compatible second source is documented, but the DSC1001 family includes other frequencies and stability grades that share the same 4-SMD footprint.
Yes — the part includes a standby (power-down) function that reduces supply current to 15 µA max when disabled.
No official second source or pin-compatible replacement is documented. Other DSC1001 series oscillators share the same 4-SMD footprint but differ in frequency or stability — confirm the BOM position before substituting.
