AD9573
FEATURES GENERAL DESCRIPTION Fully integrated VCO/PLL core
0.54 ps rms jitter from 12 kHz to 20 MHz
Input crystal frequency of 25 MHz
Preset divide ratios for 100 MHz, 33.33 MHz
LVDS/LVCMOS output format
Integrated loop filter
Space saving 4.4 mm × 5.0 mm TSSOP
0.235 W power dissipation
3.3 V operation The AD9573 provides a highly integrated, dual output clock
generator function including an on-chip PLL core that is
optimized for PCI-e applications. The integer-N PLL design
is based on the Analog Devices, Inc., proven portfolio of high
performance, low jitter frequency synthesizers to maximize line
card performance. Other applications with demanding phase
noise and jitter requirements also benefit from this part.
The PLL section consists of a low noise phase frequency
detector (PFD), a precision charge pump, a low phase noise
voltage controlled oscillator (VCO), and a preprogrammed
feedback divider and output divider. APPLICATIONS
