Timing for a two-clock-domain board
The DSC6122CI2A-00ATT: This eliminates a second oscillator footprint on boards that need both a base clock for the MCU (25 MHz) and a higher-speed reference for the PHY or FPGA (50 MHz).

Product details
Frequently asked questions
Where can I buy the DSC6122CI2A-00ATT?
The DSC6122CI2A-00ATT is obsolete per Microchip, but we source it through independent distribution. Submit an RFQ for current availability and pricing — each lot is verified for authenticity and RoHS compliance before quoting.
What is the closest alternative to the DSC6122CI2A-00ATT?
No pin-compatible successor is listed by Microchip. A functional replacement would require a different MEMS XO with the same dual-output frequencies (25/50 MHz), CMOS output, and 4-VDFN footprint — but a board spin may be needed if the pinout differs.
What compliance documentation is available for this part?
The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC). Standard Microchip MEMS oscillators are typically RoHS-compliant; confirm the specific declaration with the supplier at RFQ.
