The Renesas Electronics 8T49N287 series has two independent fractional feedback PLLs that can be used as jitter attenuators and frequency translators. It is equipped with six integer and two fractional output dividers which allowing the generation of up to 8 different output frequencies is ranging from 8kHz to 1GHz. Four of these frequencies are completely independent of each other and the inputs. The eight outputs may select among LVPECL LVDS HCSL or LVCMOS output levels.

Supports SDH or SONET and Synchronous Ethernet clocks including all FEC rate conversions
Phase slope limiting and fully hitless switching options to control output phase transients
Programmable output phase delays in steps as small as 16ps
