IDT8R43002I-01 Description
The IDT8R43002I-01 is a two output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the two frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz.
