Si47xx-EVB
IMPORTANT: Jumper Settings
Because of the many possibilities available to configure the EVB, ensure that these four jumpers are set
accordingly:
1. J41: GPO3/DCLK setting
2. J44: TX/RX setting for Audio1 I/O (automatically set by the GUI for baseboard 1.3 and later)
3. J45: TX/RX setting for Audio2 I/O (automatically set by the GUI for baseboard 1.3 and later)
4. J5, J13: Analog Audio Source, RCA or Line In
J41: GPO3/DCLK Setting
UpperâDCLK digital audio clock
LowerâGPO3 digital control signal
For configuring the Si47xx digital audio input, make sure that the jumper is set in the Upper position so that the
DCLK signal will be routed to the Si47xx.
J44: TX/RX Setting for Audio1 I/O (automatically set by the GUI for baseboard 1.3 and later)
UpperâAudio1 is set to FM transmit (pin 13 and 14 will be the digital audio input).
LowerâAudio1 is set for FM receive (pin 13 and 14 will be analog/digital audio output).
J45: TX/RX Setting for Audio2 I/O (automatically set by the GUI for baseboard 1.3 and later)
UpperâAudio2 is set to FM transmit (pin 15 and 16 will be the analog/digital audio input).
LowerâAudio2 is set for FM receive (pin 15 and 16 will be the digital audio output).
J5, J13: Analog Audio Source, RCA or Line In
UpperâRCA inputs are used for analog audio source.
LowerâLine inputs are used for analog audio source.
