PL660 Datasheet, PDF (1/15 Pages) PhaseLink Corporation – Analog Frequency Multiplier

Analog Frequency Multiplier
PL660 and PL663 XO Families
DESCRIPTION
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.
PhaseLink’s patent pending PL66x family of AFM
products can achieve up to 800 MHz differential
PECL, LVDS, or single-ended CMOS output with
little jitter or phase noise deterioration.
PL66x-xx family of products utilize a low-power
CMOS technology and are 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 PECL/LVDS, or single-ended CMOS 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.
