The Analog Frequency Multiplier (AFM) is the industry’s first ‘Balanced Oscillator’ utilizing analog multiplication of the fundamental frequency (at double or quadruple frequency), combined with an attenuation of the fundamental of the reference crystal, without the use of a phase-locked loop (PLL), in CMOS technology.PL560/5-xx products can achieve up to 800MHz output frequency with little jitter or phase noise deterioration. In addition, the low frequency input crystal requirement makes the AFMs the most affordable high-performance timing-source in the market.PL560/5-xx family of products utilize low-power CMOS technology and are housed in Green/RoHS compliant 16-pin TSSOP, and 16-pin 3x3 QFN packages.
