8T49N242

FemtoClock® NG Universal Frequency Translator 8T49N242 Datasheet General Description The 8T49N242 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 device places virtually no constraints on input to output frequency conversion, supporting all FEC rates, including the new revision of ITU-T Recommendation G.709 (2009), most with 0ppm conversion error. The outputs may select among LVPECL, LVDS, HCSL or LVCMOS output levels. This makes it ideal to be used in any frequency synthesis application, including 1G, 10G, 40G and 100G Synchronous Ethernet, OTN, and SONET/SDH, including ITU-T G.709 (2009) FEC rates. The 8T49N242 accepts up to two differential or single-ended input clocks ...
