8T49N283 - NG Octal Universal Frequency Translator

General Description

The 8T49N283 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, allowing the generation of up to 8 different output frequencies, ranging from 8kHz to 1GHz.

Key Features

  • Supports SDH/SONET and Synchronous Ethernet clocks including all FEC rate conversions.
  • Two differential outputs meet jitter limits for 100G Ethernet and STM-256/OC-768.

FemtoClock® NG Octal Universal Frequency Translator 8T49N283 Datasheet Description The 8T49N283 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, allowing the generation of up to 8 different output frequencies, ranging from 8kHz to 1GHz. Four of these frequencies are completely independent of each other and the inputs. The other four are related frequencies. The eight outputs may select among LVPECL, LVDS or LVCMOS output levels. This makes it ideal to be used in any frequency translation application, including 1G, 10G, 40G and 100G Synchronous Ethernet, OTN, and SONET/SDH, including ITU-T G.709 (2009) FEC rates.
