It outputs HCSL (High-Speed Current Steering Logic) — the differential signalling standard used for PCIe reference clocks, 100 Gigabit Ethernet, and FPGA clock trees. The ±20 ppm frequency stability holds the timing budget for most serial-link applications without external trimming.
The supply range spans 2.5 V to 3.3 V — a single BOM line covers both logic rails, simplifying inventory when the same design ships in 2.5 V and 3.3 V variants.
MEMS vs quartz — the reliability advantage
Start-up time is typically under 5 ms, compared to 10–20 ms for a quartz oscillator. The 6-VDFN package (7.0 mm × 5.0 mm, 0.9 mm seated height) is a standard footprint shared across the DSC1224 family, so a frequency change or a move to a different Microchip MEMS oscillator can reuse the same PCB layout.
No pin-compatible equivalent from another manufacturer is confirmed; the DSC1224 series itself covers multiple frequencies and output types (LVDS, LVPECL, HCSL) in the same 6-VDFN footprint.
