Features
Four Input Clocks
One crystal/CMOS input
Two differential/CMOS inputs
One single-ended/CMOS input
Any input frequency from 9.72MHz to 1250MHz
(9.72MHz to 300MHz for CMOS)
Clock selection by pin or register control
Low-Jitter Fractional-N APLL and 3 Outputs
Any output frequency from <1Hz to 1035MHz
High-resolution fractional frequency conversion
with 0ppm error
Easy-to-configure, encapsulated design
requires no external VCXO or loop filter
components
Each output has independent dividers
Output jitter as low as 0.16ps RMS (12kHz-
20MHz integration band)
Outputs are CML or 2xCMOS, can interface to
LVDS, LVPECL, HSTL, SSTL and HCSL
In 2xCMOS mode, the P and N pins can be
different frequencies (e.g. 125MHz and 25MHz)
Per-output supply pin with CMOS output
voltages from 1.5V to 3.3V
