Integrated Device Technology Synchronous Ethernet Frequency Translator 840271BGILFT

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. The input of the device accepts differential ( LVPECL , LVDS , LVHSTL , SSTL , HCSL ) or single-ended ( LVCMOS ) signals. The extended temperature range supports telecommunication and networking equipment requirements. The 840271I uses a small RoHS 6, 8-pin TSSOP package and is an effective solution for space-constrained applications.
