PL560-XX Datasheet, PDF (1/15 Pages) PhaseLink Corporation – Analog Frequency Multiplier

PRODUCT DESCRIPTION
PhaseLink’s Analog Frequency Multiplier^TM (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.
PhaseLink’s patent pending PL560-xx family of AFM
products can achieve up to 800 MHz 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-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.

FEATURES
PL560-xx VCXO Family
• Non-PLL frequency multiplication
• Input frequency from 30-200 MHz
• Output frequency from 60-800 MHz
• Low phase noise and jitter (equivalent to fundamental
crystal at the output frequency)
• Ultra-low jitter
o RMS phase jitter < 0.25 ps (12kHz-20MHz)
o RMS period jitter < 2.5 ps
