8T49N285 に関するリソース
説明
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.
Renesas’ 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.
