Slide 2: What Is Inverted MESA Blank?
What Is Inverted MESA Blank? • Traditionally, crystal blanks are fabricated by mechanical lapping and polishing to obtain required thickness. • Inverted Mesa Blank technology uses photolithography processes similar to those in semiconductor wafer manufacturing to etch out a “well” in the crystal bla

Slide 5: Why Inverted Mesa Blank? (1)
Why Inverted Mesa Blank? ( 1 ) • Oscillator frequency is inversely proportional to the thickness of the crystal blank. The higher the frequency, the thinner the crystal blanks. • Traditional polished blanks reach manufacturing limitation in thinning crystal blanks. • Inverted Mesa technology creates
Slide 6: Why Inverted Mesa Blank? (2)
Why Inverted Mesa Blank? ( 2 ) • Inverted Mesa blanks can be used in crystals, crystal oscillators and VCXOs for high fundamental frequency applications. − Excellent phase noise/jitter performance than PLL oscillators − Better ESR and startup characteristics than 3rd overtone oscillation − Eliminate
