PL560-37 Datasheet, PDF (1/15 Pages) Micrel Semiconductor – Analog Frequency Multiplier

Analog Frequency Multiplier
PL560-XX VCXO Family
PRODUCT DESCRIPTION
The Analog Frequency Multiplier (AFM) is 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 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
AFMs the most affordable high-performance timing-
source in the market.
PL560/5-xx family of products utilize low-power
CMOS technology and are housed in Green / RoHS
compliant 16-pin TSSOP, and 16-pin 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
crystal at the output frequency)
 Ultra-low jitter
o RMS phase jitter < 0.25 ps (12kHz-20MHz)
o RMS period jitter < 2.5 ps
 Low phase noise
o -142 dBc/Hz @100kHz offset from 155.52 MHz
o -150 dBc/Hz @10MHz offset from 155.52 MHz
 High linearity pull range (typ. 5%)
 +/- 120 PPM pullability VCXO
 Low input frequency eliminates the need for expensive
crystals
 Differential output levels (PECL, LVDS), or single -
ended CMOS
 Single 3.3V, ±10% power supply
 Optional industrial temperature range (-40C to +85C)
 Available in 16-pin Green/RoHS compliant TSSOP, and
3x3 QFN packages
