LVPECL is a differential emitter-coupled logic output requiring a 50-Ω to VCC-2V termination at the receiver — not a CMOS input. The 58 mA max supply current reflects the constant-current bias of the output stage, not the load.
Only if the original quartz XO also has an LVPECL output and the same 6-SMD footprint (3.20 x 2.50 mm). MEMS oscillators have faster startup and no aging drift, but the output logic family must match — LVPECL is not pin-compatible with CMOS or LVDS without a level translator or termination change.
