4.10. Differential Input Circuitry
The Si5010 provides differential inputs for both the high-speed data (DIN) and the reference clock (REFCLK)
inputs. An example termination for these inputs is shown in Figure 6. In applications where direct dc coupling is
possible, the 0.1 µF capacitors may be omitted. The DIN and REFCLK input amplifiers require an input signal with
a minimum differential peak-to-peak voltage listed in Table 2 on page 6.
