Supply voltage, temperature, and frequency stability — the fit check
The DSC6102HI1A-PROGRAMMABLE: The total frequency stability of ±50 ppm includes the combined effects of temperature, supply variation, and aging, so the clock edge at the receiver stays within a 100 ppm window over life. Typical current draw is 3 mA at maximum supply — low enough that the oscillator's contribution to the board's thermal budget is negligible, even in a densely populated multi-rail design.
Lifecycle reality — obsolete, but still sourced
This means the factory no longer manufactures it, and no last-time-buy window remains open. For existing BOM lines already qualified with this part, independent distribution channels maintain inventory. If you are designing a new board, consider the active DSC61XX family variants with the same 4-SMD footprint and pinout — the MEMS resonator and CMOS output are consistent across the series, so the PCB layout transfers with a simple order-code change.
