The DSC1001AI5-050.0000 is a 50 MHz XO (Standard) from Microchip's DSC1001 series, built on a MEMS resonator and outputting CMOS levels across a 1.8V to 3.3V supply range.
The 1.8V to 3.3V supply range lets the oscillator share a rail with a 1.8V MCU core or a 3.3V I/O bank without a dedicated regulator; the 7.2mA max active current keeps the thermal load low in the 4-SMD package.
Package and footprint for assembly
The 7.00mm x 5.00mm, 4-SMD no-lead exposed-pad package sits flat on the pad with a 0.90mm seated height — standard reflow profile; check the MSL before the bake cycle to avoid popcorning.
