PL663-19 شرح
Analog Frequency Multiplier
PL663-xx XO Families
DESCRIPTION
Analog Frequency Multipliers TM (AFMs) are the
industry’s first “Balanced Oscillatorutilizing 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 (-40C to
+85C)
Available in 16-pin GREEN/RoHS compliant TSSOP,
and 16-pin 3x3 QFN packages.
