Obsolete MEMS XO – Sourcing Reality for the BOM
This part is officially listed as Obsolete. The DSC6003CE1A-000.0000T is a blank-programmable MEMS oscillator from the DSC60XX series. It requires user programming before use, which adds a step for replacement sourcing — pre-programmed alternatives may be simpler to drop in.
AEC-Q100 Grade & Temperature Envelope
The temperature range is commercial/industrial, not extended automotive — suitable for cabin or infotainment modules, not under-hood. For a 50 MHz clock, that translates to a worst-case drift of ±2.5 kHz — well within the capture range of most automotive CAN or Ethernet PHY PLLs.
Supply & Output Compatibility
Operates from 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without a separate level translator. The CMOS output drives standard digital loads directly.
Package & Board Fit
Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The 4-pin footprint is common among MEMS oscillators — a direct replacement will share the same pad layout.
