Renesas Electronics Corporation Integrated Circuits (ICs) - Clock-Timing - Clock Generators, PLLs, Frequency Synthesizers 8T49N241-007NLGI8

The 8T49N241-007NLGI8 is a universal frequency translator and jitter attenuator designed for high-performance applications such as OTN, SONET/SDH equipment, and Synchronous Ethernet. It features a fractional-feedback PLL that allows for the generation of up to four independent output frequencies ranging from 8kHz to 1GHz, with minimal constraints on input to output frequency conversion. The device supports various output levels including LVPECL, LVDS, HCSL, and LVCMOS. This product accepts up to two differential or single-ended input clocks and a fundamental-mode crystal input, with the capability for hitless reference switching and Loss of Signal (LOS) monitoring. It offers an initial holdover accuracy of ¬±50ppB and programmable loop bandwidth settings from 0.2Hz to 6.4kHz. The 8T49N241 is programmable via an I2C interface and supports automatic/manual clock selection, making it suitable for applications requiring precise frequency synthesis and jitter attenuation. The device operates within a temperature range of -40¬8C to 85¬8C and comes in a 40-VFQFPN package.
