Supply voltage spans 2.25V to 3.6V, so the oscillator runs directly off a 2.5V or 3.3V rail without an external LDO.
Microchip lists the DSC2042FI1-F0014T as Active.
The 14-VFQFN exposed-pad package measures 3.20 mm x 2.50 mm with a 0.90 mm seated height.
Yes — the MEMS resonator replaces the quartz crystal inside the oscillator package. The output is a clean HCSL or LVPECL clock, so the downstream PLL or FPGA sees the same edge rates as a quartz-based XO. The ±50 ppm stability covers the same temperature range as most industrial quartz oscillators, and the MEMS construction is inherently more shock- and vibration-tolerant.
HCSL (High-Speed Current Steering Logic) is a differential standard with a 0.7V swing centred around 0.4V, commonly used for PCIe reference clocks. LVPECL (Low-Voltage Positive Emitter-Coupled Logic) swings 0.8V around 2.0V and is typical for high-frequency clock distribution in networking gear. The DSC2042FI1-F0014T can be configured for either, so the same oscillator part number serves both interface types on the board.
