The DSC1101DL5-020.0000 is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 20 MHz CMOS output from a 6-VDFN package measuring 2.50 mm x 2.00 mm. Supply voltage spans 2.25 V to 3.6 V — a single rail covers 2.5 V and 3.3 V logic domains without an extra regulator.
The part remains orderable for both existing production and new designs.
Any DSC1101 variant with the same 6-VDFN package and function is footprint-compatible. The key differentiator is frequency and stability — the DSC1101DL5-020.0000 is a 20 MHz, ±10 ppm device. Other DSC1101 order codes at different frequencies or stability grades share the same pinout.
Yes, it is a drop-in replacement in terms of output frequency and logic level (CMOS). The MEMS resonator eliminates quartz crystal aging and is more shock/vibration tolerant. Verify the supply voltage (2.25-3.6 V) and the Standby function pin mapping on your board before swapping.
