The DSC6121CE2A-0036T: A single oscillator sourcing two clocks reduces BOM count and board area compared to using separate XOs for each frequency, which is valuable when routing two independent clock domains (e.g., a 25 MHz reference for the MCU core and a 40 MHz clock for a USB PHY or Ethernet MAC).
The DSC6121CE2A-0036T is obsolete but available through independent distribution.
