Description:The 840271I is a PLL-based Frequency Translator intended for use in telecommunication applications such as Synchronous Ethernet. The internal PLL translates Ethernet clock frequencies such as 125MHz (1Gb Ethernet), 156.25MHz (10GbE XAUI) and 161.1328MHz (10Gb Ethernet) to an output frequency of 25MHz. The PLL does not any require external components. The input frequency is selectable by a 2-pin interface. The 840271I is optimized for low cycle-to-cycle jitter on the 25MHz output signal.
