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.

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 (-40C to +85C)

 Available in 16-pin Green/RoHS compliant 3x3 QFN

packages and as die.
