The Renesas Electronics frequency translator has one fractional-feedback PLL that can be used as a jitter attenuator and frequency translator. It is equipped with four integer output dividers, allowing the generation of up to four different output frequencies, ranging from 8kHz to 1GHz. These frequencies are completely independent of the input reference frequencies, and the crystal reference frequency. The outputs may select among LVPECL, LVDS, HCSL or LVCMOS output levels.

It accepts up to two differential or single-ended input clocks and a fundamental-mode crystal input

The internal PLL can lock to either of the input reference clocks or just to the crystal to behave as a frequency synthesizer

The device supports hitless reference switching between input clocks

The device monitors both input clocks for Loss of Signal and generates an alarm when an input clock failure is detected

The PLL has a register-selectable loop bandwidth from 0.2Hz to 6.4kHz

The device is programmable through an I2C interface

It also supports I2C master capability to allow the register configuration to be read from an external EEPROM
