The IBYPASS[5:0] signals form the Digital Received
I Channel data input bus, which supplies the I Stream to
the L64724 when the ADC is bypassed.
I Channel Data
The IVIN signal is the Analog Received I Channel data
input bus, which supplies the I Stream to the L64724.
Q Channel Data
The QBYPASS[5:0] signals form the Digital Received
Q Channel data input bus, which supplies the Q Stream
to the L64724 when the ADC is bypassed.
Q Channel Data
The QVIN signal is the Analog Received Q Channel data
input bus, which supplies the Q Stream to the L64724.
