描述 Description

The Analog Frequency Multipliers? (AFMs) are the industry’s first “Balanced Oscillator” utilizing analog multiplication of the undamental frequency (at double or quadruple frequency), combined with an attenuation of the fundamental of the reference crystal, without using a phase-locked loop (PLL), in CMOS technology.The patent pending PL663-xx family of AFM products can achieve up to 800 MHz differential LVPECL, LVDS, or single-ended LVCMOS output with little jitter or phase noise deterioration.PL663-xx family of products utilizes a low-power CMOS technology and is housed in GREEN/ RoHS compliant 16-pin TSSOP and 3x3 QFN packages.
