1-1. XTI Input
When using a crystal oscillator, connect it between XTI pin and XTO pin. Only 11.2896MHz, 12.288MHz,
16.9344MHz and 18.432MHz crystal oscillators are available. When using an external clock, the external
clock must be input to the XTI pin and the XTO pin must be open. The XTI pin should also be open when
not using XTI input.

1-2. BICK Input
A stable BICK of single frequency is required when using clock input from BICKx (x=1~3) pin as
reference clock.
