(Preliminary) Analog Frequency Multiplier
PL565-37/38 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.
The PL565-37/38 products can achieve up to 250
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.

FEATURES
Non-PLL frequency multiplication
Input frequency from 30-62.5 MHz
Output frequency from 120-250 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 < 25 ps
Low phase noise
o -147 dBc/Hz @100kHz offset from 155.52 MHz
o -157 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 or single-ended CMOS
Single 3.3V, ±10% power supply
Optional industrial temperature range (-40C to +85C)
