... REFIN are different frequencies, the multiplication factor will be adjusted to retain the same output frequency. OUT The IDT5T940 can act as a translator from a differential LVPECL, LVDS, or REG single-ended LVTTL input to LVPECL or LVDS outputs. The IDT5T940-10 has LVDS outputs and the IDT5T940-30 has LVPECL outputs. ...
