The 8T49N285 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 8 kHz to 1 GHz. Output frequencies can be completely independent of the input frequencies, and up to three of these frequencies can be completely independent of each other.The eight outputs may select among LVPECL , LVDS , HCSL or LVCMOS output levels.
The 8T49N285 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 8T49N285 can be used in GbE/10GbE/100GbE Synchronous Ethernet line card applications in order to preserve the G.8262 compliance from the Synchronous Equipment Timing Source ( SETS ) on the timing card.
IDT ’s third generation Universal Frequency Translator family also includes the 8T49N286 (4-in / 2- 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 synchronous equipment timing source ( SETS ) for Synchronous Ethernet (SyncE) and 10G-40G SyncE, respectively.
