PL663-17

Analog Frequency Multiplier PL663-xx XO Families DESCRIPTION Analog Frequency Multipliers TM (AFMs) are 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 using a phase-locked loop (PLL), in CMOS technology. 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. FEATURES  Non-PLL frequency multiplication  Input frequency from 30-200 MHz  Output frequency from 60-800 MHz  Low phase noise and jitter (equivalent to fundamental at the output frequency)  Ultra-low jitter o RMS phase jitter < 0.25 ps (12 kHz to 20 MHz) o RMS period jitter < 2.5 ps typ.  Low phase noise o -145 dBc/Hz @ 100 kHz offset from 155.52 MHz o -150 dBc/Hz @ 10 MHz offset from 155.52 MHz  Low input frequency eliminates the need for expensive crystals  Differential LVPECL/LVDS, or single-ended LVCMOS output  Single 2.5V or 3.3V +/- 10% power supply  Optional industrial temperature range (-40C to +85C)  Available in 16-pin GREEN/RoHS compliant TSSOP, and 16-pin 3x3 QFN packages.
