(AFMs) are the industry鈥檚 first 鈥淏alanced Oscillator鈥?/div>
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鈥檚 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.

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擄C to +85擄C)
Available in 16-pin
GREEN/RoHS
compliant
TSSOP, and
16-pin 3x3 QFN packages.
