(Preliminary) Analog Frequency Multiplier
PL560/565-08 VCXO Family
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 .

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 timingsource in the market.
PL560-08 and PL565-08 products utilize low-power CMOS technology and are housed in Green / RoHS compliant 16-pin TSSOP, and 16-pin 3x3 QFN packages.
