Si5022/Si5023
Differential Output Circuitry
The Si5022/23 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 16. 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.
