The DSC6102MI1A-PROGRAMMABLE: Total frequency stability is ±50 ppm, which meets the timing margin for most CAN, LIN, and Ethernet PHY reference clocks.
Lifecycle status and sourcing reality
For buyers with a BOM line that still calls out this order code, the part can be sourced through independent surplus and broker channels. Availability is lot-specific — date-code spread and packaging condition (sealed reel vs. cut tape) vary per lot and are confirmed at the time of RFQ. No pin-compatible direct replacement from Microchip exists; a board-level redesign using a current DSC61XX variant or a different MEMS oscillator family would be required for new production.
Package, footprint, and board-fit note
This compact footprint is compatible with standard pick-and-place equipment and reflow soldering profiles for 1.6 mm-thick PCBs. The no-lead construction reduces parasitic inductance compared to a leaded package, which helps maintain signal integrity at higher frequencies within the 1–100 MHz range. Surface-mount mounting on a 4-layer board with solid ground plane under the oscillator is recommended to keep supply noise below the jitter budget. The Enable/Disable pin should be pulled to the supply rail if not used; floating it may cause the output to oscillate intermittently.
