Product status is Active. No last-time-buy clock, no successor to evaluate. The DSC1124 series is Microchip's standard MEMS oscillator family, so supply continuity is tied to a mature product line, not a niche quartz cut.
If the quartz oscillator has an HCSL output and a compatible footprint (6-SMD, no lead, 5.0 mm x 3.2 mm), the DSC1124BI2-100.0000 is a direct drop-in. The MEMS base resonator is more shock-tolerant than quartz, but confirm the Enable/Disable logic polarity matches the existing circuit.
HCSL (High-Speed Current Steering Logic) — the differential current-mode output that PCIe reference clocks require. It is not LVDS or LVPECL; the termination is 50 Ω to ground on each line, not a 100 Ω differential resistor.
