Si5017
Differential Output Circuitry
The Si5017 utilizes a CML architecture to output both the recovered clock (CLKOUT) and data (DOUT). An
example of output termination with ac coupling is shown in Figure 14. In applications in which direct dc coupling is
possible, the 0.1 µF capacitors may be omitted. The differential peak-to-peak voltage swing of the CML
architecture is specified in Table 2 on page 7.
