Flexibility

The LMK6C/D/P/H BAW oscillator is a single IC (single BAW die + single base die) solution which can generate any output frequency from 1 MHz to 400 MHz – much like a PLL/VCO based quartz oscillator – however at the specs much closer to an SPXO. BAW oscillator has fast start up time (<5 ms), comes in industry standard smallest package (3.2 mm × 2.5 mm, 2.5 mm × 2.0 mm), and has a typical current consumption of 50 mA. It can operate at 1.8 V, 2.5 V or 3.3 V supply and is pin to pin compatible with all oscillator competitors. The BAW oscillator also supports all standard output types including LVPECL, LVDS, and HCSL for differential and LVCMOS for single ended.
