8 / 31 page Si5350C-B 8 Rev. 1.0 2. Typical Application 2.1. Si5350C Replaces Multiple Clocks and XOs The Si5350C is a clock generation device that provides both synchronous and free-running clocks for applications where power, board size, and cost are critical. An example application is shown in Figure 1. Any other combination is possible. Figure 1. Replacing multiple XTAL/XOs and PLLs with one Si5350C 2.2. Applying a Reference Clock at XTAL Input The Si5350C can be driven with a clock signal through the XA input pin. This is especially useful when in need of generating clock outputs in two synchronization domains; one reference clock can be provided at the CLKIN pin and at XA. Figure 2.
