Description

The 844003EI-01 is a 2 differential output LVDS synthesizer designed to generate Ethernet reference clock frequencies. Using a 19.53125MHz or 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 2 frequency select pins DIV_SEL[1:0]): 312.5MHz, 156.25MHz, and 125MHz. The 844003EI-01 is packaged in a small 24-pin TSSOP package.
