The 82V3911AUG is a single-circuit PLL from Renesas aimed at Ethernet, SONET/SDH, and Stratum timing applications. Its maximum output frequency is 644.53125 MHz.
Yes — the input stage accepts CMOS, LVDS, and PECL levels. The same three standards are available on the output. No external level translator is needed when the reference clock is an LVDS oscillator or an FPGA differential output.
The maximum output frequency is 644.53125 MHz. The datasheet should specify the minimum lock frequency and the loop bandwidth — the evidence does not carry those figures. For Ethernet and SONET/SDH line cards, this ceiling covers 155.52 MHz (OC-3), 622.08 MHz (OC-12), and 156.25 MHz (10GbE reference).
