8T49N287 FemtoClock NG Octal Frequency Translators

Renesas Electronics 8T49N287 FemtoClock® NG Octal Frequency Translators feature two fractional-feedback PLLs used as jitter and frequency translators. These frequency translators generate up to eight different output frequencies ranging from 8kHz to 1GHz with the help of six integers and two fractional output dividers. The eight different outputs can be selected among LVPECL, LVCMOS, LVDS, or HCSL output levels. The 8T49N287 frequency translators support hitless reference switching between input clocks. These frequency translators monitor all input clocks for Loss of Signal (LoS) and generate an alarm when an input clock failure is detected. Typical applications include 1G, 10G, 40G, and 100G synchronous Ethernet, SONET/SDH, wireless base station baseband, data communications, and OTN de-mapping.
