Resources for 8T49N286
Description
The 8T49N286 has one fractional-feedback PLL that can be used as a frequency translator with jitter attenuation or a frequency synthesizer. It is equipped with six integer and two fractional output dividers, allowing the generation of up to eight different output frequencies, ranging from 8kHz to 1GHz. Output frequencies can be completely independent of the input frequencies, and up to four of these frequencies can be completely independent of each other. The eight outputs may be selected among LVPECL, LVDS, HCSL, or LVCMOS output levels.
The 8T49N286 is ideal for use in a wide range of equipment, including 10G/40G/100G SONET/SDH and Ethernet network line cards, wireless base station baseband units, broadcast video, carrier Ethernet switches, OTN, or in test and measurement applications. For example, the 8T49N286 can be used in GbE/10GbE/100GbE Synchronous Ethernet line card applications to preserve the G.8262 compliance from the Synchronous Equipment Timing Source (SETS) on the timing card.
Renesas' third-generation Universal Frequency Translator family also includes the 8T49N285 (2-in/1-PLL/8-out), and 8T49N287 (2-in/2-PLL/8-out), and the 8T49N242 (2-in/1-PLL/4-out). These devices are complemented by the 82P33714 and 82P33731 SETS for Synchronous Ethernet (SyncE) and 10G to 40G SyncE, respectively.
