Overview

Register Map: Section 6.
2 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 (12kHz20MHz 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.
