ParameterLMK6C/D/P/H BAW Oscillator Specifications and DetailsQuartz Oscillator Specifications and DetailsBAW Benefits Over QuartzAdvantage
FlexibilityOne BAW die + One base die

(Singe IC solution to support any frequency, voltage supply, pin to pin compatible)

Frequency limitationsAlleviates supply constraints, single IC supports all frequenciesBAW Oscillator
Temperature Stability±10 ppm

(Maintains temperature stability irrelevant of temperature range)

As temperature increases so does ppm stabilityTighter stability at extended temperatureBAW Oscillator
Jitter

BW 12 kHz–20 MHz

125 fs max (LVDS, LVPECL, HCSL)

500 fs max (LVCMOS)

High end performs similar to BAW BAW matches well with top end of the Quartz marketSimilar
Power Supply Noise Immunity-70 dBc (Peak spur due to 50 mV injection on 3.3 V power supply from 50 kHz to 1 MHz)

(Integrated LDO)

Typically has no integrated LDONo external LDO or DC/DC converter required to optimize performanceBAW Oscillator
VibrationMIL_STD_883F Method 2002 Condition A

(In addition to MIL standard, the BAW oscillator has a typical vibration stability of ~1 ppb/g. This results in minimal phase noise impact due to vibration.)

Typically does not pass MIL-STD. Can be as high as 10+ ppb/g.Minimal impact from environmental effectsBAW Oscillator
ShockMIL_STD_883F Method 2007

Condition B (In addition to MIL standard, can withstand much higher shock levels)

Typically does not pass MIL-STD. Can fail at 2,000g.Minimal impact from environmental effectsBAW Oscillator
