The DSC6101JI1A-012.0000T: For a 12 MHz clock feeding an ECU or sensor module, the qualification saves you from having to run your own reliability screening.
Supply flexibility and package footprint
Typical current draw is 3 mA, which keeps the thermal contribution negligible in a sealed enclosure. The ±50 ppm frequency stability covers most CAN, LIN, and Ethernet PHY reference clock requirements without needing a trim capacitor.
Obsolete — sourcing through independent channels
No official successor part number is listed in the transition documentation. If you are qualifying a replacement, budget for board-level re-test of the clock jitter and start-up time.
