8T49N241-999NLGI Mounting Type, Renesas Electronics 8T49N241-999NLGI, Clock Generator, 40-Pin VFQFN

The Renesas Electronics 8T49N241 has one fractional-feedback PLL that can be used as a jitter attenuator and frequency translator. It is equipped with one integer and three fractional output dividers, allowing the generation of up to four different output frequencies, ranging from 8kHz to 1GHz. These frequencies are completely independent of each other, 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.
