Analog Frequency Multiplier
PL663-xx XO Families
DESCRIPTION
FEATURES
• Non-PLL frequency multiplication
PhaseLink’s 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.
• 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
PhaseLink’s 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.
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)
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.
• Available in 16-pin GREEN/RoHS compliant TSSOP,
and 16-pin 3x3 QFN packages.
