핀수 = 40 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.Supports SDH/SONET and Synchronous Ethernet clocks including all FEC rate conversions 0.35ps RMS Typical Jitter (including spurs): 12kHz to 20MHz Operating Modes: Synthesizer, Jitter Attenuator Operates from a 10MHz to 50MHz fundamental-mode crystal or a 10MHz to 125MHz external oscillator Initial holdover accuracy of +50ppb. Accepts up to 2 LVPECL, LVDS, LVHSTL or LVCMOS input clocks Accepts frequencies ranging from 8kHz to 875MHz Auto and manual clock selection with hitless switching Clock input monitoring including support for gapped clocks Phase-slope limiting and fully hitless switching options to control output clock phase transients
