(Preliminary) Analog Frequency Multiplier
PL565-68 VCXO
PRODUCT DESCRIPTION
The Analog Frequency Multiplier (AFM) is the
industry’s first ‘Balanced Oscillator’ utilizing analog
multiplication of the fundamental frequency (at
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.
Micrel’s world’s best performing 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
AFM the most affordable high-performance timing-
source in the market.
PL565-68 product utilizes low-power CMOS
technology and is housed in Green / RoHS
compliant 16-pin TSSOP, and 16-pin 3x3 QFN
packages.
QFN PACKAGE PIN-OUT
FEATURES
Non-PLL frequency multiplication by 2.
Input frequency from 62.5-160 MHz
Output frequency
o PL565-68: 125-320MHz
Low phase noise and jitter (equivalent to fundamental
crystal at the output frequency)
Ultra-low jitter
o RMS phase jitter < 100 fs (12kHz-20MHz)
o RMS random period jitter < 2 ps
Low phase noise
o -142 dBc/Hz @100kHz offset from the carrier
o -155 dBc/Hz @10MHz offset from the carrier
High linearity pull range (typ. 5%)
VCXO, set pullability ±100ppm ~ ±200ppm
Low input frequency eliminates the need for expensive
crystals
Differential output levels: LVPECL
Single 3.3V, ±10% power supply
Optional industrial temperature range (-40C to +85C)
Available in 16-pin Green/RoHS compliant 3x3 QFN
packages and as die.
