8T Universal Frequency Translators

Renesas Electronics 8T Universal Frequency Translators (UFT) accept one or two input reference clocks per PLL from 8kHz to 710MHz, switching between them as necessary. The devices generate any output frequency from 1MHz to 1.3GHz with no frequency translation error in most cases. Family members support either one or two different pin-selectable configurations per PLL that may be pre-loaded into the internal One-Time Programmable (OTP) non-volatile memory for automatic operation directly from powerup, or an I²C serial interface can be used to set the desired configurations. In addition to a crystal input, the UFT features two clock inputs per PLL and provides two outputs per PLL. Each output is individually programmable as LVPECL or LVDS.
