Description:The 8T49N242 has one fractional-feedback PLL that can be used as a frequency translator with jitter attenuation or a frequency synthesizer. It is equipped with four integer output dividers, allowing the generation of up to four different output frequencies, ranging from 8 kHz to 1 GHz. Output frequencies can be completely independent of the input frequencies. The four outputs may select among LVPECL, LVDS, HCSL or LVCMOS output levels.The 8T49N242 is ideal for use in a wide range of equipment, including 10G
