FemtoClock® Crystal-to-3.3V LVDS Frequency Synthesizer 844003 Datasheet General Description The 844003 is a three differential output LVDS Synthesizer designed to generate Ethernet reference clock frequencies. Using a 31.25MHz or 26.041666MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of four frequency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz. The 844003 has two output banks, Bank A with one differential LVDS output pair and  Bank B with two differential LVDS output pairs. The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above.
