The wide range simplifies BOM consolidation across designs with different core voltages.
For precision timing (e.g., Ethernet 100BASE-TX), a tighter stability grade may be needed. Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits space-constrained PCB layouts.
Yes, it is a drop-in replacement for a standard 48 MHz quartz oscillator in a 4-pin SMD package, provided the supply voltage (1.8V-3.3V) and output type (CMOS) match the existing circuit. The MEMS resonator offers better shock resistance and typically faster startup than quartz.
