7.1. WB Receiver Initialization
The first Si47xx window is the Initialization window as shown in Figure 71. On the function menu, select and
highlight the function of the Si47xx as a WB Receiver. Select the Boot Mode, Audio Mode, Firmware, Bus Mode,
and initial part settings and then click Initialize. A new window displaying "Initializing WB Receiver" will appear. If
you check "Use XOSCEN," the daughter card crystal and on-chip oscillator will be used to clock the Si47xx. You
can also select "(Analog Mode) to Analog Output", "(Digital Mode) to SPDIF and CODEC (Analog Output)", or
"(Analog & Digital Mode) to Analog Output and SPDIF" with the Audio Mode drop down menu.
Note: SPDIF will not be supported on new EVBs as of February 14, 2011. Modes of operation requiring the SPDIF will not be
available in the initialization window for those boards.
